If you haven’t checked out Santa Rosa’s Rock Star University’s House of Rock concert venue, this weekend is the perfect opportunity, as the space hosts two benefit concerts for the Anova School for Autism and Learning Differences. Friday features nationally touring Journey tribute act Faithfully, and Saturday brings Van Halen tribute band Atomic Punks, rocking out to the David Lee Roth–era of the classic group. Local teens V Squared open both shows, and 100 percent of ticket sales go to building a much-needed playground for Anova students. Sept. 29–30, at House of Rock, 3410 Industrial Drive, Santa Rosa. 7:30pm, both nights. $25–$40. rockstaruniversity.com.
