I just finished an album in a day project, based on this: http://crapart.spacebar.org/aad/
I started working on this at 8:00pm on Thursday 10/10/19. I finished the last mix of the last song in the project at 7:59pm on 10/11/19 (my nephew’s 9th birthday). The rules for the project define an “album” as 20 minutes or 30 songs. I clock in at about 21:00. Success.
