I've always been a musician, which I think is fairly common for programmers. Besides playing music I've written and arranged music as well.
Here is a little album of instrumentals I shared with friends recently. A mix of genres, jazz, world, latin and reggae (not all in the same song!) done in the past 10 years or so.
I released a little CD of instrumental music, which is on iTunes but I've never even made enough to get paid.
Music (especially composing) and programming seem to have brain cells in common; perhaps each has influenced the other over the years. Or maybe music and programming are actually the same thing in the brain and only the output format is different.
