Unheard Improvisations by Harvey Day

A few years ago I developed a process with which I could record music without monitoring what I was recording. Since then, I've been experimenting with, and refining the process.
This series is the final culmination of this time spent with the idea.
Presented as 100 unique cassette tapes with a total run time of 33.3 hours of unheard improvisations using a cassette duplicator and found/field recorded sound.

Each tape has unique hand made cover art, and 20 minutes of distinct music.
