I come from a musical family. Mom was a piano teacher for a large portion of her life, and Dad is a saxophone hobbyist who grew up in England during the heyday of Tubby Hayes and Ronnie Scott. I started taking piano lessons from my Mom, but it's too easy to slack off with your parent, so she passed me on to a friend of hers, where I got more motivated to play music by playing pop hits and TV themes. I did some classical training, but I was always more into the really thematic stuff.
Theoretical concepts of music and extended techniques are more like seasoning to me; they're not the meal. I like outside music that still has a sense of forward motion and an emotive quality to it.
