Here's a quick & dirty jam with a crappy mix. I started by sampling the bass line from Lalo Shiffrin's Bullitt theme, and went from there. The drums are canned / programmed (not sampled), and the strange, funky chorus part was made with a Dave Smith Instruments MoPho — an analog, monophonic synth.
I'm going through some old music now for two reasons: simple blog fodder to flesh out this section; and a refresher / motivator on where to go from here.
