Cain’s Ballroom welcomes dance pop duo Karmin, an act that had been known for its covers of other pop star’s hits. With the release of Pulses, Karmin’s first full-length album, in March, Amy Heidemann and Nick Noonan showed their own abilities as songwriters, no doubt honed from their time at Boston’s Berklee College of Music, where they met as students. On the road for their headlining “Pulses Tour,” Karmin take the Cain’s stage with a new single, “I Want it All,” on Wednesday, April 30. Bonnie McKee opens for the pair at 8 p.m. Tickets are $19-$35 at www.cainsballroom.com.
