There were a lot of pretty solid local compilation albums released in the past year, but the latest installments of Zia Records' "You Heard Us Back When . . " series stand out because of their breadth. We're calling YHUBW "local" compilations, but they actually pull together bands from the three areas the 30-year-old chain calls home: Phoenix, Tucson, and Las Vegas. We can't speak for Vegas and Tucson, but the curators did an excellent job of picking some of our city's most interesting acts. Volume 4, which came out in April, for example, starts out with three well-known local acts (Dust Jacket, Kirkwood Dellinger, Matthew Reveles) before exposing some equally interesting but much less prominent acts like Gooder and The New F-O's. Not everything is gold — Volume 3 features a song by VW Trainwreck, possibly the worst band in the state — but that's sort of the charm of it. If you're looking for a local comp, you don't just want to hear bands that don't suck — it's nice to get a feel for the scene as a whole, maybe with a little comic relief. Any post-Monkees band that records its own theme song, as the all-too-appropriately named Trainwreck did on the compilation is at least good for a few laughs, and we thank the good folks at Zia for providing them.
