A straight-ahead distorted riff, an atmospheric overlay I really like, and a final section in 7/4.
I have around 10 more sketchbook entries in the queue, so I believe I will try to post #52 right before New Year's, and then shift directions. Future song-like ideas of this sort will go to future albums-a-day or other "real" music. I will continue with a sketchbook once-a-week thing, but I think I will try something less song-like that will better leverage the public-domain aspect.
Hmm, my uploads these days seem to be at 256Kbps... I thought I only had 128Kbps, but I don't really remember.
