Don’t fret if you missed Cat Power when she performed at Sixth and I a few weeks ago; D.C.’s Real Clothes explores a similar strain of the warped Appalachiana that Chan Marshall was toying with about a decade ago. Anchored by the dusty vocals of Nico Fox, the band gets dirty with its roots-rock influences, caking acoustic guitars and fiddles in hiss while it ruminates on love and communication. This weekend, Real Clothes performs a benefit show for Casa Ruby, a D.C. nonprofit that supports the Latino LGBT community. They’ll be joined by the equally lo-fi Raw Feels, from Fredericksburg, Va., who sound like a lost side project of Sebadoh or Pavement with plenty of drone and mumbled vocals. Rounding out the bill is Lilac Daze, which pulls equally from the sophisticated twee pop of The Pastels and the bratty scuzz punk of Times New Viking. The band has a taste for gustatory-styled songs, like “Pumpkin Pie Haircuts” and “Drinking With an Ulcer.” Just avoid that second pasttime during the show. Real Clothes performs with Lilac Daze and Raw Feels at 7 p.m. at CD Cellar, 2607 Wilson Blvd., Arlington. Donations requested.(703) 248-0635. cdcellarva.com.
