As a sort of sequel to Starving Artist, The One Man Band works pretty well. It keeps the pattern going of "artist creates a thing for cash/fame," and I like that the general art style was maintained. It makes it feel like it's all in the same neighborhood, heh. The music mechanic itself works really well, because it's simple enough for anyone to use, and the musically skilled can probably do really well with it.
Good job on this, dev. I had fun making noise.
