Rob Mazurek’s Alternate Moon Cycles was International Anthem’s first release. The incredibly spare single-note-centered cornet, bass and organ chant was recorded to tape at pint-sized Chicago bar Curio as part of a performance series that predates any notion of our label’s existence. Documenting this performance – highly unique even within the depths of Mazurek’s vast catalog – stirred those notions, and soon talks began of releasing the recording on a fresh imprint.

Performed by Mazurek with Matthew Lux and Mikel Patrick Avery, the music unfolds glacially amongst the gentle creaks, clinks, whispers, and scuffles of the active room. It’s difficult to imagine a more honest rendering of the two sidelong pieces of organic minimal music, and nearly impossible to separate the sounds from their performance context.

Now this long-gone gem of supernatural frequency excavation is back in print, wrapped in our IARC 2025 obi strip, with a new 4-page insert booklet featuring additional session photos and fresh liner notes by Mikel Patrick Avery.
