Forgot to mention the Coltrane/Monk record, outstanding. Plus, yes, I did enjoy the Decembrists record, they're incredibly consistent from release to release. No doubt seeing them live would have sealed their standing for me in '05.

Also forgotten, I really liked the Bjork release in '05 - The Music from Drawing Restraint 9. Not a Bjork record in some ways, but very rewarding mood music.
