From the blog "The Incessant Noise, rare and forgotten experimental music."
I enjoyed the vivid description of the music in the second paragraph:
"Circular Thoughts" was composed in 1974, and was first released in a version for gamelan. This here is a solo clarinet version played by Goode himself.
"Circular Thoughts" starts on some very quick ostinati, with a nice melodic pattern. The real meat of the piece begins a couple of minutes in. After a short silence, the clacking of the clarinet keys can be heard without any notes. Goode slowly, quietly begins blowing in the clarinet, and doesn't let up much for the duration of the piece. An exploration of circular breathing techniques, the material of the piece is really just a fast ascending modal scale repeated endlessly, but Goode accents different notes at different points, pulling melodies out of the repeated figure. The accented notes then slowly recede back into the texture of the scale pattern. At times, the effect makes it sound like several instruments playing, not through any multiphonics or anything, just by having a repeated textural bed with individual notes popping out. At times it almost sounds like a solo version of Steve Reich's early phasing music, which doesn't make any sense but there you go.
Towards the end of the piece Goode starts to throw in some traditional scottish (?) melodies now and again, making a nice little contrast to the repetitive stream of scales before. Incredibly beautiful, meditative, and probably my favorite piece of music for a solo, monophonic instrument.
