I've seen them 3 times. The first was during Lollapallooza ('95 i think?), and i wasn't very interested. The second was right after my favorite album of theirs (NYC Ghosts & Flowers) had just came out, and it was in a nice seated theater. I remember thinking that they were getting some
beautiful guitar sounds, great use of delay and feedback.
Then i saw them last year in this sweatbox club in NYC, and just didn't feel it at all.
I have heard horror stories about when they play "solo" gigs, and your post confirms those stories.
