Pardon my digression, but...
I just applied there! How easy is it to break into the Music scene at Northeastern?
Sorry for missing your post. If you try REALLLLY hard to get to know everyone that plays here, you'll run into everyone pretty quick. It'll make more sense when you're here, but basically you just have to be in the couple of places where all the players/bands go. There's only one place here (Ryder hall, where the music department and practice rooms are) so it's not too hard.
If you want to start a band here, it's basically the same thing. Meet all the bands, go to the student groups involved with the bands, and basically just talk to everyone that goes through Ryder Hall.
