Pink Floyd
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. At the same time they wrestled with lyrical themes and concepts of such massive scale that their music has taken on almost classical, operatic quality, in both sound and words. Despite their astral image, the group was brought down to earth in the 1980s by decidedly mundane power struggles over leadership and, ultimately, ownership of the band's very name. After that time, they were little more than a dinosaur act, capable of filling stadiums and topping the charts, but offering little more than a spectacular recreation of their most successful formulas. Their latter-day staleness cannot disguise the fact that, for the first decade or so of their existence, they were one of the most innovative groups around, in concert and (especially) in the studio.The Rolling Stones
By the time the Rolling Stones began calling themselves the World's Greatest Rock & Roll Band in the late '60s, they had already staked out an impressive claim on the title. As the self-consciously dangerous alternative to the bouncy Merseybeat of the Beatles in the British Invasion, the Stones had pioneered the gritty, hard-driving blues-based rock & roll that came to define hard rock. With his preening machismo and latent maliciousness, Mick Jagger became the prototypical rock frontman, tempering his macho showmanship with a detached, campy irony while Keith Richards and Brian Jones wrote the blueprint for sinewy, interlocking rhythm guitars. Backed by the strong yet subtly swinging rhythm section of bassist Bill Wyman and drummer Charlie Watts, the Stones became the breakout band of the British blues scene, eclipsing such contemporaries as the Animals and Them. Over the course of their career, the Stones never really abandoned blues, but as soon as they reached popularity in the U.K., they began experimenting musically, incorporating the British pop of contemporaries like the Beatles, Kinks, and Who into their sound. After a brief dalliance with psychedelia, the Stones re-emerged in the late '60s as a jaded, blues-soaked hard rock quintet. The Stones always flirted with the seedy side of rock & roll, but as the hippie dream began to break apart, they exposed and reveled in the new rock culture.Janis Joplin
The greatest white female rock singer of the 1960s, Janis Joplin was also a great blues singer, making her material her own with her wailing, raspy, supercharged emotional delivery. First rising to stardom as the frontwoman for San Francisco psychedelic band Big Brother & the Holding Company, she left the group in the late '60s for a brief and uneven (though commercially successful) career as a solo artist. Although she wasn't always supplied with the best material or most sympathetic musicians, her best recordings, with both Big Brother and on her own, are some of the most exciting performances of her era. She also did much to redefine the role of women in rock with her assertive, sexually forthright persona and raunchy, electrifying on-stage presence.
