My experience with him was fairly decent. In fact, that was the first of the 3 October Philly gigs I was able to nail down. The only difficulty I encountered in dealing with him is that he's only available to discuss bookings on Monday evenings.
By the way, I see from my notes that he offered me October 8th (along with the 12th and a couple of other October dates) when I spoke with him in July, and he told me at the time that there would also be a DJ on that date. We did agree that there would be also be a local band on the bill for the 12th (since organissimo had not yet performed in Philly and a local band could help be a draw). The band he scheduled as the "warm-up" for organissimo on the 12th is Dr. Ketchup, a jazz-funk group that should fit well with organissimo. You can hear some samples and read about them here.
