Debut albums are always so good. I think this has to do with the band deciding that they finally are ready to make an album (songs good enough, etc.). They wouldn't want to record an album until they have a lot of songs and experience in most cases, and with a lot of songs to choose from, it would only make sense to choose the best ones. Labels might play a part in this as well, as debut albums are usuall on indy, small, or self-owned labels. Obviously, this would enable the band to basicly do... whatever the shit they want! And we all know that's where the best music comes from.
