I'm a songwriter/harmonica player/guitarist, based in Brooklyn and Ithaca, NY. For the last few years I've been focusing on a self-created genre called "harmonitronica," a combination of harmonica and electronica.
Harmonitronica fuses the organic and vocal nature of the harmonica with the layering and atmospherics of ambient music, the beats of electronica, and the unpredictability of found music, noise and chance. It is not computer music. It is not carefully constructed with software, but improvised live, using loopers and other effects, and recorded direct to two-track, usually a Zoom H4N. It's allowed me to combine two seemingly divergent musical passions: I've played the harmonica for more than half my life, and I've loved certain kinds of electronic and experimental music for even longer than that.
I used to use ProTools and GarageBand pretty heavily, but I have almost entirely abandoned them. The only pre-recorded sound you will hear on my harmonitronica work are samples and some sequencer rhythms. I do use Audacity to edit my live improvisations when they get too long, or to clean up dead-ends.
