Play from the heart! It will set you apart. Show up VERY prepared. When I did the auditions for Trisha Yearwood and Deana Carter, I was told to learn five songs. I learned their whole catalog! Now I’ll see those people around, backstage or whatever, and I’ll get the nod. Like, “I remember you dude. Thanks for learning my material.” It shows respect to the person that’s hiring you, and that you value them as an artist enough to sit down and truly prepare.
