According to Charleston, S.C.-based "sloppy-tonk" duo Shovels & Rope, its stripped-down setup (two guitars and a "junkyard drum kit harvested from an actual garbage heap") is about necessity. Cary Ann Hearst and Michael Trent are an onstage two-person band and offstage married couple who have honed their sound into a "harmonized, loose but tight, streamlined audience killing machine." The band’s forthcoming album, O' Be Joyful, is set for release at the end of the month, but the duo’s reputation is already growing. Shovels & Rope return to Jack of the Wood on Saturday, July 7. Wylie Hunter & The Cazadores also perform. 9 p.m., $8. http://jackofthewood.com.
