Could I send in a rendition of a rock song as part of the Art Supplement?

<p>I'm a pretty good guitarist and vocalist and I mention these things in my ECs but I never expanded on them in my essay. I only worry that what I may do may not be as highbrow, or "sophisticated". Most kids send in classical Violin or Piano and I might end up uploading Nirvana. I just don't know if colleges want to hear that. Any thoughts?</p>

<p>This is also for U Chicago, if that makes any sort of difference.</p>
