Infinite Loop Theory and the Boys in the Band

I am incorporating infinite loop theory into a story about a group of talented teens who go out on tour. One of the boys has captured a 'string' and has no idea of it's potential -- of course that's because I have no idea of its potential! Sound and music seem logical, but what about electromagnetic waves, static, magnification? Any ideas? What can the string do for him, for the band, for his love life?
