Another animated Library of Congress stereograph. "Skating on the lake, Central Park, New York, N.Y., U.S.A.". Circa 1902.
When I was in college, I skated on Lake Winnipesaukee once. There were only four of us on the ice. We'd cleared off a section of the […]

My very final track for #Noisevember. I've had a great time churning out noise this month, I hope you've enjoyed listening. This last one is a calming coda of swelling noise, composed using a recursive method I've been playing with for a while. Has a nice long quiet tail. Cheers! […]

#noisevember! The last day! In keeping with this month's theme, one more escalator-related composition, this time made from a field recording I did a while back of a very noisy escalator at the light rail station in Seattle I most frequent. Layers, etc. Enjoy! […]

#noisevember! Tried a little live-processed flute. I've had this flute for 50 years, since 4th grade, but have not played it at all for many years. Processed it with Csound, doing the delayed-copies-of-the-signal-interfere-with-each-other-spectrally thing. I […]
