I love Laurie Anderson. Remind me, some time, to tell the stories of seeing her live. I have that on CD somewhere, but don't remember it beyond confirmation that yes, it was mostly an art piece, not that there's anything wrong with that. I should dig it out and give it another listen.
George -- I am not Craig, but: Big Science and United States I-IV Live.
EDIT: Oh, and without a doubt:
I wasn't at the New York show, but I was at the DC show just a couple days earlier, but immediately after 9/11, and it was just her and her backing band, with no performance art whatsoever, and it reminded me just how powerful she is with even just her music.
