So, jonah B plays a mean guitar, and has a special touch with synth sounds. when I find somthing new by him, I go ahead and fire up the keyboard, because there's usually somthing great to play along with. Sometimes I wind up expanding the tune deeper by a few tracks.---okay. So, it's me on the Right, and JB on the left. drag on the mic to fade back and fore betwixt. if this works smoothly, and entertains some people, I think it'd be cool to get 3 or 4 people to cover a tune for a 4-way mash-up.
