D'oh! Man, am *I* ever having a Monday!!! Snakes and Arrows is actually the one I don't like. Vapor Trails is OK.
#17 Heard? I've got all of them (even if I can't--apparently--tell the damned difference today). My favorite band EVAR (I knew wheel had to have SOME redeeming quality). I even have that album of covers they did...and I guess there is a second album of theirs I don't really care for.
If you haven't seen them live, do so before you (or they) die. They always put on a great show. Considering they've been at it for some 30+ years, and how particular they are about their gear and sound, I have to wonder how much longer they will keep touring.
