I am also a musician (bass, acoustic guitar, and a bit of drums). Writing and playing music is more of a hobby and stress reliever for me though as I have no desire to pursue that professionally. I'd hate to be "that guy" who is 30+ years old and still thinks his crappy band can make it big.
I grew up watching/loving Star Wars (Episodes IV-VI) so I definitely have a geeky/nerdy side that's been a part of my life through the years. I love science fiction, video games, comic books, etc. I like to describe myself as your stereotypical geek/nerd except that I don't live in my parent's basement, I actually have social skills, and I'm not afraid of girls haha. It would be great if you shared this geeky/nerdy quality as well but I won't hold it against you if you don't.
I love spending time in big cities, especially NYC, but could also totally see myself going Thoreau on everybody's ass and moving into a cabin on the lake in the middle of the woods.
