Montgomery Gentry has exited the roster of Columbia Nashville, their label home throughout their career. The duo charted their first single for the label, “Hillbilly Shoes,” in 1999. Their No. 1 hits include “If You Ever Stop Loving Me,” “Something to Be Proud Of,” “Lucky Man,” “Back When I Knew It All” and “Roll With Me.” A compilation EP planned for a release later this month has been shelved. Columbia Nashville merged with the RCA label group in 2004 to form what is now Sony Music Nashville.
