Here's a great vid of Thurston's improv set in Doornroosje Nijmegen during the Ex festival.

He did a "regular" song set at Tivoli Utrecht last night, and some poems too. I was expecting an improv set too, but it was still mighty fine. Especially the last song Ono Soul where he jumped into the audience. No vids yet.
The Ex set was sooo good. Why oh why haven't I ever seen that band live before?
