What to do on a cloudy, wet, windy, cold spring day? Work on music in my cosy darkroom/music studio, go for a walk out to the river in the rain, capture the above photo, and finish an improv for this post. I created “In a Vacuum Improv” by playing the rhythm guitar and a bass line over a recording I made of a vacuum pump the Iceman used to suck moisture out of the refrigeration system when he repaired our floral refrigerator. The pump made such interesting sounds and rhythms, I simply had to record it. I added a couple of percussion tracks, and played the lead guitar to finish it out. I say it’s an Improve, because I only played the lead guitar once through.
