He has also written or co-written several of Big & Rich's songs with Rich, as well as singles for Gretchen Wilson, Jason Aldean, McBride & the Ride, and Tim McGraw. His first solo single, "Long After I'm Gone," was released to country radio on August 3, 2009, from the album The Quiet Times of a Rock and Roll Farm Boy.
