Several ago I started posting the individual tracks used in recording some of my music. The intent was to allow others to download the tracks and try re-mixing them. I called this the Open Source Music Project and created a website and podcast on iTunes to support the effort. Looking back, it seemed self-serving, so I took down that site.
Here is an archive of some of the music I had posted. I created all of the music using a combination of synth tracks and acoustic guitar.
