I just released a 3-song EP (and they are indeed "songs") entirely recorded/synthesized/performed in PD:

I arranged the the pieces in Audacity, just to be consistent in using open-source tools from start to finish. I think it sounds a little different from what you might expect from PD - in fact, at a patching circle a while back a PD guru called one of the songs "lowbrow." Lower your brows, then, and listen!

Thanks to everyone whose patches & ideas I used or was inspired by.
