Yeah, I went to GIT and they save all the performaces on tape for their library. I saw this performace and many others in their library.
(Just having access to the library was worth the tuition to be honest with you. That and the live performaces is where I learned the most. (The classes were mundane, I felt.)
Anyway, I think this performace was just as his Flex- able album came out. He was selling it at the show. He performed The Attitude Song and Viv Woman I think? And he talked a lot to the students and took questions. I still remember some parts.
1) He talked for a while about playing 10 hours a day at Berklee. ( Crowd goes, "Wow!!"

)
2) He took Questions and someone asked him how old he was and he said "25". The crowd was stunned and went, "Wow"

. I think eveyone thought he was way older than that by the way he played and acted.
I would love to get a copy myself. Email me if anyone can get it.
