Thanks for all the replies!
I spend about 3 - 4 months there every year, but broken up over the year. I'll be there in May, July, and probably again in the fall. For some reason I've never connected to the music community in the city, but would love to as I spend more time.
I've looked at NIME, but I think I'm going to be working while it's on and won't be able to go to the main conference. However, if there are concerts or other events in the periphery I'd love to meet up and check them out.
