Mule is best described as sounding like a backwoods clamor, and their debut is one of the more distinctive offerings of the 90s. Taking field hollers and other basic Americana-based lyrical content (with plentiful helpings of cursing and lewd rhyming, such as "My dick's as hard as Chinese arthimetic"), Mule tied them to the stripped-down, but loud and noisy guitar of P.W. and the thundering rhythm section of Kimball and Munro. Munro also sang, and some of the more memorable Mule songs (Pent, Mama's Reason to Cry, Rope and the Cuckold) are call-and-response numbers between the two singers. Kimball was the driving force behind the first album, and the EP Wrung.
