The concert of Zucchero in San Francisco, at the Palace of Fine Arts was great! My only problem with it was the sound system, which was not well calibrated: it was very loud (which is OK) but with a lot of distortions... It wasn't well adapted to the room.
Sadly the average age was very high.... with a lot of old fogeys like me.... This is sad because it means that younger people don't know Zucchero well, a loss for them.
I like the fact that Zucchero is a no-nonsense performer, not a show-off. His band was wonderful, with musicians who are top-notch.
