Companion piece to Kid A and the resemblence is unmistakeable one can easily see that they are from them same sessions. Not as immediately bracing and engaging as Kid A. Less focused in approach so can't help but seem less groundbreaking and forward looking. It has some stellar moments, however; Pyramid Song, You and Whose Army, Knives Out, I Might Be Wrong and Morning Bell which is unexplicably on both Kid A and Amnesiac. But there are also pieces of 100% filler. Can't help but wonder how great an album we would have ended up with they had released just one all killer / no filler album from these sessions. Still a fine album that I was happy to discover 3.5 stars
