7. Emerson, Lake and Palmer
Emerson, Lake and Palmer get a bad rap. Some critics (particularly punk rock fans) say their name makes them sound more like a law firm than a rock band, and that they signified everything wrong with the bloated arena rock of the late 1970s. People say they single-handedly inspired the punk revolution. That's an awful lot to pin on a single rock group, and even if that's true – it's quite the accomplishment. Haters aside, it's hard to deny songs like "Lucky Man," "Karn Evil 9" and their rendition of "Fanfare For The Common Man." The group began as a prog-rock supergroup featuring members of the Nice (Emerson), King Crimson (Lake) and Atomic Rooster (Palmer). They merged classical music with prog and were packing arenas by the mid-1970s, but times changed and they quickly grew to despise one another. There have been periodic reunions over the years, and just last year they played a one-off gig.
