 | | Brought together in Stockholm by guitarists Peter Lindgren and Mikael Åkerfeldt in 1990, Opeth added progressive influences and acoustic instrumentation to their brand of Swedish death metal. |
 | | A sort of instrumental prog-rock/prog-metal supergroup, Liquid Tension Experiment features Dream Theater's John Petrucci (guitar) and Mike Portnoy (drums), keyboardist Jordan Rudess (who has worked with the Dixie Dregs and has since joined Dream Theater), and bassist extraordinaire Tony Levin (King Crimson, Peter Gabriel, and many others). |
 | | If there is one group that embodies progressive rock, it is King Crimson. Led by guitar/Mellotron virtuoso Robert Fripp, during its first five years of existence the band stretched both the language and structure of rock into realms of jazz and classical music, all the while avoiding pop and psychedelic sensibilities; the absence of mainstream compromises and the lack of an overt sense of humor ultimately doomed the group to nothing more than a large cult following, but made their albums among the most enduring and respectable of the prog rock era. |
 | | Marillion emerged from the short-lived progressive rock revival of the early '80s to become one of the most enduring cult acts of the era. |
 | | Drummer Mike Portnoy (Dream Theater, Liquid Tension Experiment) had a brainstorm that gave birth to the band Transatlantic. |
 | | Over the course of their decades-spanning career, Canadian power trio Rush emerged as one of hard rock's most highly regarded bands; although typically brushed aside by critics and rarely the recipients of mainstream pop radio airplay, Rush nonetheless won an impressive and devoted fan following, while their virtuoso performance skills solidified their standing as musicians' musicians. |
 | | Far and away the longest lasting and the most successful of the '70s progressive rock groups, Yes proved to be one of the lingering success stories from that musical genre. |
 | | Drawn together by a shared love of metal and prog rock, Riverside were founded in 2001 in Warsaw, Poland, by Mariusz Duda (vocals, bass, guitar), Piotr Grudzinski (guitar), Piotr Kozieradzki (drums), and Jacek Melnicki (keyboards). |
 | | Michael Romeo formed Symphony X in New Jersey in 1994. The original lineup of the group also included Thomas Miller (bass guitar), Rod Tyler (vocals), Jason Rullo (drums), and Michael Pinnella (keyboards). |
 | | Sweden played a crucial part in the progressive rock revival of the 1990s, but amid dark-sounding King Crimson-influenced bands like Anekdoten and Anglagard, the positive-thinking Yes-enlightened act the Flower Kings felt almost out of place. |
 | | The progressive metal outfit Ayreon is essentially just Dutch multi-instrumentalist and songwriter Arjen Anthony Lucassen (formerly of the more mainstream metal band Vengeance), plus a revolving-door cast of collaborators and guest musicians that changes from project to project. |
 | | Camel never achieved the mass popularity of fellow British progressive rock bands like the Alan Parsons Project, but they cultivated a dedicated cult following. |
 | | Pink Floyd is the premier space rock band. Since the mid-'60s, their music relentlessly tinkered with electronics and all manner of special effects to push pop formats to their outer limits. |
 | | Steve Hackett is best known as the guitarist with Genesis during their best years as both a progressive and commercial band, across ten albums of their history. |
 | | The word "supergroup" has often been used to describe O.S.I., one of the best-known progressive metal/progressive rock acts to emerge in the United States in the 2000s -- and considering who has been leading O. |
 | | Formed at the dawn of the progressive rock era in 1969, Gentle Giant seemed poised for a time in the mid-'70s to break out of its cult-band status, but somehow never made the jump. |
 | | A band from another time, Ozric Tentacles served as the bridge from '70s cosmic rock to the organic dance and festival culture that came back into fashion during the '90s. |
 | | Emerson, Lake & Palmer were progressive rock's first supergroup. Greeted by the rock press and the public as something akin to conquering heroes, they succeeded in broadening the audience for progressive rock from hundreds of thousands into tens of millions of listeners, creating a major radio phenomenon as well. |
 | | Few hard rock bands are as widely respected yet criminally overlooked as King's X. The trio (bassist/vocalist Doug Pinnick, guitarist/vocalist Ty Tabor, and drummer/vocalist Jerry Gaskill) seemed destined for the big time with their irresistible blend of melodic Beatlesque harmonies, metallic riffing, and prog rock detours, yet for reasons unknown, never truly broke through to a mainstream audience. |
 | | Not all hard rock 'guitar heroes' that emerged during the late '80s-early '90s were instrumental solo artists, as evidenced by Dream Theater's John Petrucci. |
 | | When prog rock first reared its head during the early '70s, it contained elements of hard rock, but few bands crossed the line into heavy metal. |
 | | David Gilmour gained international fame for his incisive, atmospheric guitar work and vocals with Pink Floyd, and eventually became the leader of the group during their late period as well as pursuing a successful solo career and working with some of the most respected names in British rock. |
 | | Tool's greatest breakthrough was to meld dark underground metal with the ambition of art rock. Although Metallica wrote their multi-sectioned, layered songs as if they were composers, they kept their musical attack ferociously at street level. |
 | | Jordan Rudess has the distinction of taking classical piano training at the Juilliard School of Music at nine years old. |
 | | Formed in the 1980s, IQ is comprised of Martin Orford, Paul Cook, Mike Holmes, Peter Nicholls, and John Jowitt. |
 | | Picking up the pieces from At the Drive-In, Cedric Bixler-Zavala and Omar Rodriguez-Lopez formed the Mars Volta and wasted little time branching out into elements of hardcore, psychedelic rock, and free jazz that expanded on the boundaries of their previous work. |
 | | Along with teaching some of the top rock guitar players of the '80s and '90s, Joe Satriani is one of the most technically accomplished and widely respected guitarists to emerge in recent times. |
 | | Throughout his career, guitarist Robert Fripp has continually pushed the boundaries of pop music, as well as pursuing many avant-garde and experimental musical ideas. |
 | | Although they were initially grouped with the legions of pop-metal bands that dominated the American heavy metal scene of the '80s, Queensrÿche were one of the most distinctive bands of the era. |
 | | The history of Renaissance is essentially the history of two separate groups, rather similar to the two phases of the Moody Blues or the Drifters. |
 | | Six-string wizard Steve Vai, along with his one-time teacher Joe Satriani, set the standard for rock guitar virtuosity in the '80s. |
 | | Genesis started life as a progressive rock band, in the manner of Yes and King Crimson, before a series of membership changes brought about a transformation in their sound, into one of the most successful pop/rock bands of the 1980s and 1990s. |
 | | Set a course for Planet X, full speed ahead. No, Planet X is not the newest sci-fi film; it is actually a progressive rock/fusion band headed by keyboardist Derek Sherinian (Kiss, Alice Cooper, Dream Theater, Platypus). |
 | | An eye-opening trip to San Francisco's Haight-Ashbury during the summer of 1967 inspired British-born drummer Chris Judge Smith to compose a list of possible names for the rock group he wished to form. |
 | | Born April 25, 1958, in Edinburgh, Scotland, Derek William Dick (aka Fish) was the dramatic lead vocalist for prog rock band Marillion until beginning a solo career in 1988. |
 | | In 1984, Daniel Gildenlow formed the band Reality at the whopping age of 11. The group stayed together under that name for seven years, albeit not without personnel changes. |
 | | Echolyn's style has been termed updated progressive rock, due to the band's classically trained, highly professional members -- vocalist Ray Weston, guitarist/vocalist Brett Kull, keyboard player Chris Buzby, bassist Tom Hyatt and drummer Paul Ramsey. |
 | | With nearly as many lineup changes as one of their influences, Yes, Arena was one of the dominant neo-prog groups of the 1990s. |
 | | Born Christopher Russell Edward Squire, in Wembley, England, on March 4, 1948, Chris Squire's main claim to fame is as the bassist for prog rock super heroes Yes. |
 | | Caravan was one of the more formidable progressive rock acts to come out of England in the 1960s, though they were never much more than a very successful cult band at home, and, apart from a brief moment in 1975, barely a cult band anywhere else in the world. |
 | | As the leader of Genesis in the early '70s, Peter Gabriel helped move progressive rock to new levels of theatricality. |
 | | Often compared to Yes for their melodicism and Gentle Giant for the complexity of their compositions, Happy the Man added their own high-caliber musicianship, a sense of symphonic drama, odd time signatures, spacy sound, and occasional whimsy to their brand of progressive rock. |
 | | Jethro Tull was a unique phenomenon in popular music history. Their mix of hard rock; folk melodies; blues licks; surreal, impossibly dense lyrics; and overall profundity defied easy analysis, but that didn't dissuade fans from giving them 11 gold and five platinum albums. |
 | | Born in Perivale, Middlesex, England, Rick Wakeman's interest in music manifested itself very early, and from the age of seven on he studied classical piano. |
 | | Starcastle (along with Styx, Fireballet, and Kansas) were part of a belated stateside response to British progressive rock. |
 | | Born as John Roy Anderson on October 25, 1944, in Lancashire, England, Jon Anderson would grow up to become one of the most recognizable voices in progressive rock. |
 | | The group Yes has had a long and complicated history. By 1989, there were two different factions, one led by bassist Chris Squire that owned the rights to the name "Yes," and this one, featuring singer Jon Anderson, drummer Bill Bruford, keyboard player Rick Wakeman, and guitarist Steve Howe. |
 | | Before the seeds of the Flower Kings were planted, Kings' guitarist/vocalist Roine Stolt was working in the band Kaipa. |
