I have a company in New York City producing music for commercials, for radio, TV, features, etc. That's how I've been making my living. And now the company is very successful - to the extent that I can afford to come out and play.
When I select a topic, it's usually a commitment of two to three years of my life.
My parents both worked full time. I remember a lot of simple meals. Everything I know about cooking is self-schooled.
