If you go to Berklee, you will end up with many connections in all three major cities. A slim majority goes to LA, the next largest group to NYC, and the remainder to Nashville. At least those that end up doing/trying to do music professionally. A lot of Berklee grads end up moving back to where they came from, or staying in Boston and starting real estate or tech careers. One of the better trumpet players I knew back then is doing real well as a golf instructor in Texas. To the OP: Really take that Adam Neely video at the top of the thread to heart. He and I went there at the same time (graduated 2009), and came away with a lot of the same conclusions about music school. If you've got any other Berklee or NYC questions feel free to shoot me a private message.
