Always a crowd pleaser, Brave Combo mixes up styles with strong sections of polka, rock ‘n’ roll and Latin jazz in their signature sound. Their rich music embodies the tapestry of spirit in American culture. This Sunday night’s Cat’s Cradle show is also a fundraiser for the Cystic Fibrosis Foundation and kicks off with locals Imperial Pints. The show starts at 7 p.m.; tickets are $10.
