Art Supplement

<p>Hey, I've been playing electric guitar for 4,5 years and I feel I should submit an Art supplement to Colleges with my application. The thing is I really don't know what to record? I mean...I can cover some songs like "The Loner- Gary Moore" , "Can't Stop -RHCP" or even the solo of "Tornado of souls" to demonstrate my leve of technique. I can improvise over a Blues/Funk/Rock backing track or record some of my own songs.
Seriously, I don't know what to choose. What should I demonstrate? Technique? Improvisation , or Composition? Or all of them? Or maybe whatever I want ? :P</p>
