There are a lot of cover bands in town, but few could boast a front person as commanding as vocalist Laura Jane Wilcock of The Tighten Ups, who perform at the Tiki House on May 20. The band excels at classic horn-backed rock and soul, from Creedence Clearwater Revival and The Rolling Stones to Sam & Dave and Jr. Walker, with Wilcock’s brassy vocals and bawdy humor making the group a tough act to follow. The seven-piece band seems to be a tight squeeze for the intimate Tiki House, but if you’re a fan of R&B or you’re just looking for a great time, you won’t want to miss this show. The Tighten Ups perform at 9 p.m. on Friday, May 20 at The Tiki House, 1152 Garnet Ave. Cover TBD. 21 and up. www.myspace.com/thetightenups
