Look, good rock ’n’ roll doesn’t have to be complicated. Take Heartless Bastards, a four-piece, fronted by singer-songwriter Erika Wennerstrom, that cleaves close to the center line but seldom fails to satisfy. Alberta Cross, a rock project of Swedish singer-songwriter Petter Ericson Stakee, opens the 9 p.m. show at Port City Music Hall (504 Congress St., Portland). Tix: $15-$18 ($30 preferred seating; 18+). 800-745-3000. portcitymusichall.com.
