This video installation, “Years,” from artist Bartholomäus Traubeck, uses an optical… something… to “read” a thin cross section of a tree (the “record”) and translate it in to piano music.
If you watch the video all the way through, you’ll notice that there are different types of records. The first is from a fir tree, and the second is from an ash with (notice the difference in texture between the two).
YEARS is from artist Bartholomäus Traubeck; watch it on Vimeo.
