Rolling Stone's 50 Greatest Prog Rock Albums of All Time

You need time to deal with Lateralus — a lot more than the seventy-seven minutes it takes just to play the whole disc. And for much of that time, you will wonder: What the fuck is going on here? Drums, bass and guitars move in jarring cycles of hyperhowl and near-silent death march.

Future Days sets its sights a little lower. Suzuki mostly sticks to the background, aside from a peculiar attempt at a pop song ("Moonshake"); the rest of the album is three long, dreamy pieces that suggest Can had been listening to electric-era Miles Davis.

The Dark Side of the Moon is a fine album with a textural and conceptual richness that not only invites, but demands involvement.
