Music Supplement (Non-classical)

So my main instrument is bass guitar and I was wondering whether or not I should include a music supplement in my application (I’m still a junior so I have some time). I don’t play any classical and my traditional jazz repertoire is limited, but I can play some technical modern, jazz-influenced things (Snarky Puppy, Vulfpeck, etc.), funk, and rock. I’ve been called to do some studio work professionally with some pretty big name people (can’t say too much because the album hasn’t been released yet) and I’ll probably be talking about music a lot throughout my application, so I’d like to have something to show colleges, but I haven’t seen too many music supplements that aren’t classically based. Any thoughts or advice?
