Here are my super-subjective Radiohead eras:
Early: Pablo Honey, The Bends
Epiphany: OK Computer, Kid A
Middle Searching: Amnesiac, Hail to the Thief
Maturity: In Rainbows, King of Limbs, A Moon Shaped Pool
That middle searching period is not as legendary as the "epiphany" high point or the latest successes of a more mature band. But there is still a lot to love there. "Sail to the Moon" is such a strange song, both beautiful and ugly, with an ending that dissembles itself with abrupt, rapid key changes into vapor.
It's one of the best examples of the prettiness of Thom Yorke's long falsetto voice.
So many great instrumental choices.
A feeling like almost no time signature at all.
