I took a couple life drawing classes, some cartooning ones, but mostly learned what I know by myself, watching how others went about their work and putting in a crazy amount of practice drawing whenever, whatever and whomever I could.
As time went on, I had to get a "normal" job, well normal jobs, and make some money for stupid things like eating. I worked with my Pop setting tile when I was a kid, sauntered around in a bunch of record stores (Licorice Pizza, Sam Goody, Music Plus, Tower Records), worked briefly as an insurance fraud investigator, worked at a recording studio up in L.A. until the bullshit of that business broke me, sat dazed at a telephone survey place for a bit, and spent some years working at an AV company too.
Then one day, sitting there, going over invoices for people that I couldn't stand any more, I decided it was time to break off and gamble on doing what I've loved my whole life, drawing, making music and making movies.
So now with a buttload of mediocre to decent songs, a growing library of movies released and the drawing / design thing sheepishly paying a bill here and there, things are movin' along.
