Cortez the Killer (Backing Track)

I’ve been wanting to record and work on my own stuff but I have an issue with an external drive so not much I can do for now. I decided to throw this backing track into Logic and play some shitty runs over it (I’m on the left). Here is the backing track I used. I tried to fatten it up a little but the results aren’t so great. Not much you can do when you have drums, bass, and a rhythm guitar all on one track.
