I thought Petrucci was great but Satriani blew him away, no surprise I guess but it was the first time I saw either of them. Long show, 3.5 hrs with 2 short intermissions after Collen's and Petrucci's sets but it never dragged. Nice mix, going from hard-rocking blues to prog metal to Satriani. Petrucci had the drummer from DT with him and another bass player; he really shredded. I only went because of the $20.18 New Years promotion, but I would go again.
Oh yeah, the place was the Merriam, this cool old theater (saw Crimson there last fall), less than 2000 capacity. The bargain seats were in the next-to-last row in the top balcony. The day before the show though, their ticket office called and upgraded us to 21st row orchestra, so I was in an extra good mood for the show lol.
