I've neve heard anything outside of 69 Love Songs, but that album is a masterpiece.
And at the risk of sounding pretentious, it's not even the music that I like best about it. It's the audacity. The guts, the balls, the chutzpah if you will, that it took, to just make a triple-disc, 69 song conceptual album about love, some songs minute-long sketches, other full overblown ballads. It's a masterpiece for that alone, and unfathomably it's probably the only triple album I've heard that I couldn't edit down to a single disc when pushed.
I mean for god's sake, I'm not sure I could even write 69 SHIT songs in the time it took him to make this album, and I'm not sure I've written 69 decent to good ones in the eight or nine years I've been writing.
Aside from that, it's a hell of an album on musical merits alone. My favourite is 'I Don't Believe In The Sun.'
I hear he released an album composed entirely of feedback. THat's pretty bitchin'.
