After working together for more than a decade, longtime management partners Bob Titley and Clarence Spalding have gone their separate ways, sources say.

After working together for more than a decade, longtime management partners Bob Titley and Clarence Spalding have gone their separate ways, sources say.

The Nashville pair's flagship client, Brooks & Dunn, will stay with Spalding, as will Terri Clark and new Sony artist Ashley Monroe. Titley will oversee the careers of Clay Walker, the Ragsdales and Matt King.

Titley began managing Brooks & Dunn prior to their first album, "Brand New Man," in 1991. Spalding came on board in 1993, primarily to oversee Brooks & Dunn's touring efforts, although his responsibilities broadened considerably over the ensuing decade.

Titley-Spalding was acquired by TBA Entertainment in 1998. TBA, which was purchased early this year by a group led by Irving Azoff, has since divested itself of its management division.
