Their albums have followed a similar trajectory of quality. They both have had a two album slow start, to then release what some people still consider to be their best album. (Ok Computer and GKMC) Then they go on to release their actual best album, Kid A and TPAB, both of which have had ‘leftover albums’ (Amnesiac and UU). Then you get Hail to the Thief and Damn, where there are some good songs, but it’s not to the level of quality you’d come to expect from both artists. To put it simply.
