Bright Eyes.
"A Collection Of Songs Written And Recorded 1995-1997" was a hideous debut, way too long, poorly produced, horribly performed. Even the CD reads 'if he
was bright, he'd have released an EP'. Luckily the album that followed WAS listenable, and the one after that was better, and so on and so forth. I can't think of a band that gets
this noticeably better by each album.
