I took guitar a while back, and my heart wasn't in it at the time, but I'm ready to try it again. I sing in the car, at home - it's a huge part of my life, especially since I'm from Tennessee.
When I'm rhyming it's all in my head... Like the slaves, when they were picking cotton, they would block out their minds. They would sing.
