Purely improvised, this is just me, my piano, and my Linux studio (e.g. Soft Synths such as QSynth and ZynAddSubFX, a MIDI sequencer called MUSE, and Ardour). Everything I need to have a good time by myself. With the help of a pot of coffee this was produced entirely in an afternoon and it shows it, but that's okay, I enjoy it and I hope you will too. If there is enough interest in it I can provide the MIDI source file and the full Ardour files upon request. It needs some work, but I probably won't have much more time to work on it.
