[TRIBUTE] This may be sacrilege to Pink Floyd fans, but rather than spend a lot of money to see Roger Waters perform songs by his old band when he appears here in September, you’ll probably have just as good a time with Brit Floyd, and without having to sit though any Waters solo tunes. Not to be confused with the four-man The Machine, the Floyd tribute band that has played numerous times in Western New York over the past few decades (including two Artpark shows), Brit Floyd features eight musicians and six backing singers for a show that is heavy on latter-day Floyd; their two sets (no opening act!) include most of Dark Side of the Moon and songs from every subsequent album, including four tunes from 1994’s The Division Bell, the closest thing to a true Floyd album after The Wall. Expect a spectacular light show that may look even better from “the hill” (where all of you who didn’t get there as soon as the gates opened sit) than it will for the fans who paid for front of stage tickets. Brit Floyd comes to Artpark this Tuesday, July 18; first set starts at 7 pm.
