Toby Keith's Show Dog Records and Scott Borchetta's Big Machine Records have ended their partnership after just six months. Keith still owns a financial stake in Big Machine, but otherwise the partnership is over, according to Billboard magazine. With both labels signing several newcomers they wanted to introduce, Keith and Borchetta cited the increasing number of releases from new artists as a reason for the split. Show Dog's first album, Keith's White Trash With Money, will be released April 11. So far, Big Machine has released only one album, Jack Ingram's Live, Wherever You Are.
