ok... here's the report:
before the show, they played uncut zappa concert footage from the 70s... which got several standing ovations.
Dweezil and the gang played a lot of the old favorites... sort of a greatest hits collection, which is to be expected.
Napoleon Murphy Brock did almost all the singing, except when Terry Bozzio came out for the second set and played a few of his classics (punky's whips, tryin' to grow a chin).
Dweezil was a very mellow and understated stage presence. his playing was excellent (on his dad's old Gibson SG), but sometimes it almost seemed like he was intimidated by his father's ghost. He didn't really command the show, the way frank would have.
Steve Vai didn't come out until the second set, after Bozzio's turn in the spotlight. i'm not much of a fan of shredders, but Vai and Dweezil had some really good guitar duels... although the warm, tubey sound from Zappa's SG was a little overwhelmed Vai's ultra-bright guitar-hero sound. Dweezil didn't showboat... Vai did (and brought the house down).
The band was incredibly tight, although not as spontaneous as Frank's old bands were.
Overall, the evening was a fantastic tribute, if not quite equal to the real thing.
