Amnesiac

Perhaps the greatest sequel since The Godfather Part II, Amnesiac was the second half of the one-two punch Radiohead began with 2000’s Kid A. It was smoother on the surface yet just as disorienting underneath, putting more emphasis on the guitars its predecessor relied on less, but in all kinds of warped and mutated forms: “Knives Out” soared like vintage Smiths, and “I Might Be Wrong” rode an Allman Brothers riff into loose hip-hop hinterlands. The piano nightmare “Pyramid Song” remains terrifying, even if few understand the meaning.
