Progressive rock, often shortened to prog rock, is a music genre that shot up the charts in the late 1960s and early 1970s. The genre combined multiple popular styles of the time, including rock, punk, and psychedelia.
The “progressive” title referred to the innovative methods of sound composition and musical styling. Artists pulled from classical roots like jazz and rock but typically used new technology and modern approaches for sound and lyrics.
We’ve gathered a list of 23 of the greatest and most famous prog rock bands of all time to showcase the best artists that helped create the genre. Read on to learn about these fantastic bands.
1. Pink Floyd
Formed in 1965, Pink Floyd was likely the most famous progressive rock band and even one of the most famous bands in history that has lasted for several decades (with a few breaks in between).
Starting in London, the original Pink Floyd lineup consisted of Roger Waters, Richard Wright, Nick Mason, and Syd Barrett. David Gilmour joined in 1967.
Syd Barrett left the band in 1968, and Roger Waters took on the frontman role as it entered its golden age of popular albums and progressive rock ideas.
The band’s famous concept album, The Dark Side of the Moon, was released in 1973 to critical acclaim, particularly the album’s single, “Money.” Just in March 2023, the album celebrated its 50th anniversary.
With roots in Toronto, Canada, the group Rush formed in 1968, though the group’s members cycled a bit before settling. Rush’s lineup at its height consisted of lead vocalist and bassist Geddy Lee, drummer Neil Peart, and guitarist Alex Lifeson.
In 1977, Rush began to see significant success and attention for the band’s grasp on progressive rock.
The band’s best-selling album, “Moving Pictures,” was released in 1981 and cemented the group’s status as a progressive rock legend. The album received quadruple-platinum status in Canada and quintuple-platinum status in the United States.
With a name as simple as Yes, you might expect the same from the band’s music. But Yes’s music is anything but, featuring complex music matched by interesting conceptual themes and stunning visuals.
Yes is one of the bands on this list that are still active today, though the lineup has changed constantly since the band’s start in 1968, with a total of nineteen members in the group at one time or another.
With 22 total studio albums, the band has a lot of material to pull from, though the most popular albums are Fragile (1971) and 90125 (1983).
4. King Crimson
If you were surprised by Yes’s long list of band members, get ready for King Crimson, a group that boasts 22 members in different lineups over the years. Known for its big sound and constant change, King Crimson is one of the most influential bands in prog rock history.
The band was one of the earliest to dip into the prog-rock genre and inspired many later groups. With a 53-year-long history, King Crimson has never seemed stuck in one place musically as founder Robert Fripp encouraged innovation always.
The band’s debut album, In the Court of the Crimson King in 1969, is their most well-known and successful, featuring the long-lasting hit “21st Century Schizoid Man.”
English powerhouse band Genesis was initially formed in 1967 by a group of teenagers attending boarding school. Now, the band is one of the most successful and famous rock groups.
The band’s most successful album, Invisible Touch, was released in 1986 after a two-year break. Rumors spread at the time that the band had broken up, but in reality, they had agreed to pay attention to solo careers and came back with this megahit of an album.
The year 2010 saw the group inducted into the Rock and Roll Hall of Fame. Genesis has had breaks over the years, but they are actively creating new music currently.
6. Dream Theater
Founded in 1985, Dream Theater is a progressive rock and metal group that helped merge the two genres seamlessly. The band started as a project for the founding members who attended the Berklee College of Music but quickly became the member’s primary focus.
In 1992, the band saw widespread success by releasing their second album, Images and Words. The album’s first single, “Pull Me Under,” is the band’s most successful song and jumped into the Billboard Top 10.
The band was nominated for three Grammy Awards, and in 2012, Dream Theater won Best Hard Rock/Metal Performance for their 2021 song “The Alien.”
Along with Dream Theater, Tool is one of the most famous bands to successfully merge progressive rock and metal genres. Consisting of Maynard James Keenan, Danny Carey, Adam Jones, and Paul D’Amour (later replaced by Justin Chancellor), the band formed in Los Angeles in 1990.
Tool’s focus on conceptual themes, stylistic innovation, and visual performance helped elevate the band’s status among fans. They famously avoid releasing lyrics for their songs because they believe the sound is more important than anyone’s interpretation.
Tool’s 2001 album, Lateralus, debuted at #1 on the Billboard charts and won a Grammy for one of the album’s songs, “Schism.” The song peaked at #2 on both Alternative Airplay and Mainstream Rock charts.
8. Jethro Tull
Focused initially on blues rock, English band Jethro Tull quickly dove into the emerging progressive rock scene. The band saw early success with its British folk-rock album, Stand Up, which was released in 1969.
The band’s longest-standing member, Ian Anderson, made waves with fans early thanks to his unique use of the flute incorporated with classic and progressive rock themes.
The band’s successful 1971 album, Aqualung, is one of the best examples of a concept album to date, a staple of the progressive rock genre. The album’s title track is the band’s bestselling track and has been widely praised.
9. Porcupine Tree
Next up, Porcupine Tree is a cult classic progressive group featuring influence from other bands like Pink Floyd and Tangerine Dream. The band was founded by English musician Steven Wilson in 1987 as a joke between friends but became a legitimate project.
The band’s early years focused on classic progressive rock and psychedelic rock influences, but in 2002, Porcupine Tree saw success with infusing metal into their sound. The band’s progressive metal album In Absentia remains their most famous.
The band’s sound earned the praise of musicians who cite Porcupine Tree as a significant influence in their work in all genres, from electronic to metal.
10. Frank Zappa & The Mothers of Invention
Progressive rock as a genre is typically filled with bands, but Frank Zappa was one of the few solo artists to excel in the world of art rock both in and out of a band.
Famously, Frank Zappa experimented with nearly every genre under the sun. His early work with his band, the Mothers of Invention, consisted primarily of experimental and progressive rock.
The album Apostrophe (‘), released in 1974, is Frank Zappa and The Mothers of Invention’s most famous and successful released work. The album showcased a mix of progressive rock, jazz, and hard rock and reached the top 10 on the Billboard chart.
11. Emerson, Lake, & Palmer
Formed in 1970, Emerson, Lake & Palmer was a London-based group that helped popularize the use of synthesizers and organs as a key element of the progressive rock sound. The band comprised of Keith Emerson, Greg Lake, and Carl Palmer.
The band dominated the 1970s progressive rock scene, as they were one of the most successful mainstream acts for experimental music. The band’s self-titled debut album was released in 1970 to high praise, reaching the #4 spot on the UK music charts.
The band’s 1972 album, Trilogy, is one of the clearest examples of how progressive rock fused the worlds of classical, jazz, and rock music.
Out of Kent, England, Caravan started as an offshoot of the psychedelic rock band the Wilde Flowers. The band was a frequent presence at English music festivals in the late 1960s and early 1970s.
The band’s most famous album, In the Land of Grey and Pink, was released in 1971 and featured a mix of psychedelic and progressive rock. The album wasn’t as commercially successful as hoped, but it received high praise from critics and remained a popular progressive rock album to date.
The band’s lineup has changed over the years, but Caravan is still active and creating innovative music, including a recent 2021 album release, It’s None of Your Business.
13. The Moody Blues
If progressive rock is the topic, the English band the Moody Blues have to be a part of the conversation. Starting in Birmingham in 1964, they were one of the earliest bands to adopt the experimental sounds and stylings of progressive rock.
True to their name, the Moody Blues originally began as a blues band, but the members quickly found themselves interested in the brand-new progressive rock scene.
In 1966, the band released their second album, Days of Future Passed, which many people cite as the first executed concept album, a key aspect of the later progressive rock genre.
14. Gentle Giant
Even in a genre as complex and far-reaching as progressive rock, Gentle Giant was one of the more unique bands. Many progressive rock bands incorporated classical components, but this group frequently pulled from less mainstream inspiration, including baroque and medieval music.
In addition to unique classical components, Gentle Giant also mixed rock with big band-style jazz elements. The band was active from 1970 to 1980 and never saw mainstream commercial success, but they’re fondly remembered as a high point in the 1970s progressive rock boom.
The band’s cult following in the 1970s has only grown as people have recognized their innovative and unique sound. Give them a listen, and find out for yourselves why.
15. Tangerine Dream
The progressive rock movement saw heavy concentration in England and some pockets of the United States, but Tangerine Dream showed that the German scene could offer a special twist on the genre’s key elements.
Tangerine Dream is one of the leaders of electronica music, and the fusion of electronic with progressive themes helped set the band apart. They are often seen as the creator of cosmic rock, Germany’s answer to the popular genre of space rock.
The group has released over one hundred albums since its founding in 1967, though the albums Phaedra (1974) and Cyclone (1978) are excellent examples of their progressive electronic sound.
16. The Alan Parsons Project
Born out of the famous Abbey Road Studios, the Alan Parsons Project was a progressive rock group that combined contemporary sound with incredible sound quality. The group was the brainchild of Alan Parsons and Eric Woolfson.
Parsons was a successful audio engineer and producer that worked on albums from the Beatles and Pink Floyd. Woolfson was a talented pianist that saw potential in combining forces with Parsons.
When the two came together, the result was some of the most original and inventive music inspired by science fiction. The group’s 1977 album I Robot is their most successful, along with the 1982 Grammy-nominated Eye in the Sky.
17. Aphrodite’s Child
Although Aphrodite’s Child had a shorter run than a lot of the other progressive rock greats, they managed to create some of the highest-praised songs in the genre. The band was formed in 1967 in Greece by former members of successful bands Idols and the Forminx.
Surrounded by regressive politics, the group left for London, where they could be a part of the progressive and psychedelic rock movement.
The band’s albums were critically acclaimed, but they saw enormous success from their single releases. The 1968 single “Rain and Tears” charted high in multiple countries.
With a name straight from a 19th-century science fiction novel, it’s no surprise that the German band Eloy was an early pioneer in progressive and space rock. The band’s frontman and guitarist, Frank Bornemann, founded the group in 1969. He is the longest-standing member of the still-active band.
Although krautrock, an offshoot of experimental rock, was popular in Germany, Eloy was one of the earliest bands to bring progressive rock with blues influence to the music scene in the country.
A perfect example to listen to is the band’s 1975 album, Power and the Passion. It is a concept album that follows a consistent story through every track.
19. Procol Harum
Hailing from Essex in England, Procol Harum was one of the earliest bands to adopt the progressive rock sound. The band is famous for its start as a proto-prog band, the movement that directly preceded progressive rock.
The band saw massive success with an early single, the song “A Whiter Shade of Pale,” released in 1967. The song fits right into the theme of 1967’s summer of love and charted consistently in the United Kingdom and the United States.
When the song was added to the Rock and Roll Hall of Fame singles category in 2018, the band was also inducted with it.
The London group Hawkwind is one of the bands that helped shape the genre of space rock. This is an offshoot of progressive and psychedelic rock, merging the two themes and focusing on ethereal sounds, ambient noise, and cosmic atmospheres.
Hawkwind likes to tell a story with its music, often heavily inspired by new and old themes in science fiction. Their albums are consistently cited as an influence for bands focused on psychedelic space rock.
Active since 1969, the group has a lot of history to pull from and has incorporated other genres into their work, including metal, punk, and hard rock.
The 1970s saw the best years of progressive rock, and a band like Camel is one of the greatest examples. Not many bands were able to display the key themes of progressive rock as cleanly and front-facing as this band.
Camel is famously linked with Caravan, another of the underground prog rock greats that played in Canterbury at the time when Richard Sinclair of Caravan joined their band.
The band’s 1975 album The Snow Goose is inspired by the Paul Gallico novel of the same name that focuses on the themes of friendship amongst war.
Founded in 1969, the English group Renaissance is one of the best groups to showcase the classical influence in progressive rock. With a foundation of rock, the genres of folk and classical are the most present in the band.
Renaissance’s 1978 single “Northern Lights” helped propel them to a larger audience, as fans in the United Kingdom and the United States began to follow the group closely.
The band is still active today, though the lineup has changed over the years and now features many American members.
23. Wishbone Ash
Heavily inspired by the American jazz movement and British folk music, Wishbone Ash started out in 1969 in Devon, England. They are famous for their use of twin lead guitars, as they are one of the first bands to use the method.
Wishbone Ash’s 1972 album Argus is the band’s most successful and acclaimed album, featuring the revered song “The King Will Come.” The song showcases the twin lead guitars, along with a building drumbeat and stacked harmonies.
Though the band has had a few lineup changes over the years, they are still active now. The current members are Andy Powell, Bob Skeat, Mark Abrahams, and Mike Truscott.
