21. Camel, 'Mirage' (1974)
The classic Camel lineup occupied a unique niche in progressive rock, specializing in fluid, spacey ensemble workouts – rarely as flashy as Genesis, never as bombastic as Emerson Lake and Palmer. "We're considered a progressive band, by default, really," guitarist-flautist Andy Latimer told Will Romano for his 2010 book Mountains Come Out of the Sky: The Illustrated History of Prog Rock. "I always thought that people like Yes and King Crimson and ELP were much more obscure than Camel. They were probably better players and consequently got into much more complicated material, which made it even. . . less accessible." The quartet's second album, Mirage, fulfills their debut’s scattered promise, with Latimer and keyboardist Pete Bardens leading the rhythm section through breezy instrumentals (the contemplative "Supertwister") and expansive multi-part suites (the Lord of the Rings–themed "Nimrodel/The Procession/The White Rider").
