In the panoply of vocal stylings, it would seem like deadpan would be the easiest thing to pull off. And for those adopting it because they lack the emotive firepower to do much else, maybe it is. But adopting a deadpan for just the right effect takes considerable verve, and Mary Timony is great at it. Best-known from her time in Helium and the indie-rock supergroup Wild Flag, Timony nowadays fronts Ex Hex, whose debut album “Rips” (Merge Records) is a killer set of amped-up garage rock (expertly captured on tape by North Carolina pop deity Mitch Easter) with Timony’s coolly distant voice serving as counterpoint. Ex Hex will show it off Saturday at Carrboro’s Cat’s Cradle as part of Girls RockNC Rally: 10-Year Anniversary Celebration. Also on the bill are Mount Moriah, Shirlette Ammons, The Julie Ruin, Pink Flag and more. Doors open at 5 p.m. and bands will be playing both the main Cradle and the smaller Back Room. Tickets are $27-$29. See catscradle.com for details.
