The driving force behind this show is Numbers on Napkins. The Phoenix band is a quick-paced, simple pop-punk band, ideal for those who love Blink 182 and Bayside. It formed out of the ashes of Yars' Revenge, and if you remember that band, you deserve a gold star. Show openers Helen's Wheels is punk rock, too, but not quite as mainstream -- gritty, with shout-style vocals reminiscent of Stretch Armstrong. The band just formed earlier this year, but the members have known one another for a decade, which might explain why it sounds cohesive.
Besides the fine lineup, this show is a way to support a longtime friend to the local music community. If a bunch of unsigned musicians can offer up money and time to help, you should be able to spare a little of your own.
