Carmack, who stars as openly gay country star Will Lexington on the ABC drama, recently broke into the world of pop music with his independently released EP, Pieces of You.
Last year, the former star of The O.C. told ETonline,
"I've always been performing music and writing songs and recording songs, but on a very small-scale operation. It wasn't until I became involved with Nashville
that I thought I had opportunities to record my music in a way that I would want to put it out into the world."
