Jars of Clay is a four-member Christian rock band formed at Greenville College in Greenville, Illinois. The band has been praised for the unique mix of pop, folk, rock, and mild electronica, as well as for the graceful way they communicate their beliefs through their music. The poetic overtones, acoustic guitars, and programmed drum loops of their early work have led people to refer to them as a Christian Rock and/or alt rock band, in spite of the band's lack of a permanent drummer and bassist.
