Yr Knives is a Chicago instrumental quartet built around two very different guitar voices. The band came together sideways: composer Paul Karner wanted guitarists Andrew Trim and Brian Sulpizio to play disparate parts on a recording of his own, and when the two finally rehearsed together, a band fell into focus. Trim leads the groups Hanami and Retroreflector; Sulpizio is the constant behind Health and Beauty. Anchoring them are two Chicago mainstays, bassist Douglas McCombs (Tortoise, Eleventh Dream Day) and drummer Quin Kirchner. Two of them come up as rock and roll players, two as jazz players, and the music lives in how closely they listen across those languages.

Their debut, Begin Yr Singing, centers on two overdriven guitars merging into something neither could produce alone, over a rhythm section that can lock a groove or let it drift. The result is exploratory but grounded, "a searching music," in Trim's words, that asks questions it doesn't always answer and shifts from one performance to the next. Recorded live in a single room at Chicago's Palisade studio with Nick Broste engineering and mixed by Cooper Crain with Sulpizio, the six tracks draw on Sonny Sharrock, Neil Young and Crazy Horse, Albert Ayler, Erik Satie, and Television. The band has toured supporting The Messthetics.
