Gorillaz, "Clint Eastwood" Instrumental
The backing track for this hit song is famously based on the "Rock 1" preset on a Suzuki Omnichord. It gives you a steady platform to jam out in E-flat minor. These instrumental tracks seem to be unauthorized (on youtube) or sound-alike karaoke (on streaming). You could also jam over the original, of course.
