Saw him last night playing with Michael Macarthur. Wow! He was very accessible and what a player!
He was playing upright and mentioned that he has his own studio. I asked him about his amplification-all Epifani, but very aggressive both in his attack and volume. Light strings, low action. His upright playing, to me seems informed by electric. Also, his F-holes were stuffed with foam, I assume to prevent feedback.
The others on stage were all top players, including Jeff Lorber, yet Brian stood out!
