Logo Design for Cincinnati Winter Blues Experience IV

This is a yearly blues music festival. I am designing a t-shirt. I have the back image all set but I need something for the front. A full size logo to go across the chest or a smaller pocket sized logo. Would like it to have some sort of music or guitar theme to it. The shirts will be black so I would like the logo to be greyish / white with some blue.
