American Authors, the Mowgli’s and Echosmith at Mohawk outdoor. Although Boston rockers American Authors didn’t release their debut album until 2014, they already were widely known thanks to heavy TV-ad use of their song “Best Day of My Life,” which became a top-20 single in 2013. They’re joined on this bill by energetic Southern California band the Mowgli’s, whose spontaneous ACL Fest rain-out pop-up gig was a big hit last year, and sibling quartet Echosmith. $18, 6:30 p.m. doors, 912 Red River St., mohawkaustin.com. — P.B.
