Absolutely agree with Zeppelin. For King Crimson, did Islands precede Larks Tongue? If so, I would add that to the list. For Little Feat, I would include Time Loves a Hero. I would add Pink Floyd (everything from Meddle through Division Bell) and the Moody Blues (who really had quite the run (Days of Future Passed, In Search of the Lost Chord, On the Threshold of a Dream, Seventh Sojourn, Every Good Boy Deserves Favor, Question of Balance -- not in order). Finally, the first two Santana albums were fantastic -- Santana and Abraxas. Good thread -- I'll have to check out Wire.
