The Disquiet Junto is a weekly audio assignment, basically. Here’s a rolling playlist. I’ll bump the date whenever I contribute.
Here’s how the guy behind the Junto describes it:
The Disquiet Junto is a group I founded on Soundcloud.com. The purpose of the group is to use constraints to stoke creativity. Each Thursday evening I post a clearly defined compositional assignment, and members of the Junto are to complete the assignment by 11:59pm the following Monday. The initial Junto assignment was made on January 5, 2012, the first Thursday of the new year.
At the end of each year I compile my contributions on Bandcamp, if you want to download a chunk of them more easily.
