There’s not much depth in the output from Flesh Wounds, the young Carrboro, North Carolina, trio that’s two guitars and one drum kit, but there is a hefty amount of sweat and snot in today’s 12 O’Clock Track, “Bitter Boy.” Released in mid-May by Merge—the Durham-based mega indie label that obviously heard the local hype—the single is a ringing, high-treble thrasher of a rock ‘n’ roll song. Not even a two-minute party. It’s anthemic in its clatter and I refuse to believe there’s even a remote chance that this band isn’t a blast live. Fortunately, we all get to find that out on June 19 when they open for Mr. Elevator & the Brain Hotel at the Empty Bottle. Hooray.
