I was browsing C.net because MatthewVanitas summoned me to the forums for a Chemnitzer emergency, and it occurred to me I had never posted anything about my NaSoAlMo* 2013 entry. Only one song ended up using my [Chemnitzer] concertina: "One By One"
*NaSoAlMo is National Solo Album Month. The idea is to write and record an entire album's worth of music in the month of November, all by yourself. No previously written songs, no help from other musicians, engineers, etc. The result of my effort is here: Difficult Fractionations.
2013 was my first try at it. I'm not sure if I will do NaSoAlMo 2014. Maybe some others here will!
