re: painkiller at tonic

so, did Patton only play on the 2nd set on Fri night? If so, I really got lucky. I thought Hamid Drake was a great drummer and has a nice groove but it was completely absent of the metal feeling that Mick Harris gave the group. It was also nice to see Patton perform on 1 regular mic with no effects. He started off by doing Tuuvian (forgive me if I spelled that wrong) throat singing. I never heard him do that before. Actually, I've never seen anyone do that live. Has he ever done that on recording before?
