16 Horsepower was an American alternative country music group based in Denver, Colorado. Their music often invoked religious imagery dealing with conflict, redemption, punishment, and guilt through David Eugene Edwards's lyrics and the heavy use of traditional bluegrass, gospel, and Appalachian instrumentation cross-bred with rock. For the bulk of its career, the band consisted of Edwards, Jean-Yves Tola, and Pascal Humbert, the latter two formerly of the French band Passion Fodder. After releasing four studio albums and touring extensively, the group broke up in 2005, citing "mostly political and spiritual" differences. The members remain active in the groups Woven Hand and Lilium.
