This site promotes making music by writing an album in one day with no outtakes and using no ideas from before the day. A lot of the results are quite enjoyable. I just got done listening to Tom 7's "Quad Emotional Damage", which is all the more impressive for having been made under such tight time pressure.

If any musicians are reading this, I'd suggest trying it, otherwise there's a lot of good stuff there to listen to.

Musical equivalent of NaNoWriMo? Interesting.
