i was actually agreeing with you. i prefer most of what mogwai and mono have done to spiderland, and i thought tweez was horrendous. the fact is though, that spiderland is considered a more important album, baggage or no, and again the fact remains that mono and mogwai have no released anything really "important," deserving or no. certainly great music though.
i'm not really trying to defend spiderland. there are others who can do that better than i if they care to and like i said i think mogwai and mono have put out a lot better stuff. but spiderland will probably always be held up on a pedastal and to be honest it is a pretty excellent album.
