A Little Ice-Breaker

I have a dog named Jolly the Puggle, I'm a classically trained violinist and pianist, everyone in my (human) family has a first name composed of 4 letters except me, I have electronic music in my DNA, I love technology and the great outdoors and try to do my part to reconcile the two, I think Isaac Asimov and Philip K. Dick were geniuses, I've been to 5 continents and I am dead-set on getting to all 7, my son listens to Erik Satie every night going to bed, I bike to work, I will eat every kind of taro-based dessert there is.
