Not only does the Australian duo An Horse sound like a punkier version of Tegan & Sara. Lesbian singer and guitarist Kate Cooper and drummer Damon Cox are shadowing the Canadian town lesbian duo. The duo first gained attention as Tegan & Sara's opening act three years ago, and is now touring in support of album Walls, produced by Howard Redekopp, long associated with, well, you-know-who. An Horse opens for Kevin Devine, who has previously opened for Bob Mould. Wednesday, Oct. 19, at 8 p.m. Red Palace, 1212 H Street NE. Tickets are $14 day of show.
