this is my take on adding an instrument to the excellent "music for one musician" by Wester Skies Motel (https://soundcloud.com/regonsch/music-for-1-musician-so-far)
well, it started with one instrument, but went downhill quickly from there with one piano leading to another, which led to a bass, drums, and a clarinet recording by Stefan Thaens (http://ccmixter.org/files/stefsax/9081)
all I can say in my defence is that the original guitar really caught my imagination.
new version is 98 bpm. made entirely in Reason 7 and on new headphones I haven't gotten fully used to yet, so the bass/treble balance might be off.
