I'm from around the area and can definitely feel the lack of Dubstep in and around Boston. After visiting NYC one day last year, the difference was almost like night & Day. Actually all forms of EDM and even Hip-Hop has always suffered in Boston. There was actually an article I read a few days ago that explained the situation pretty well:

I respect the promoters putting on great shows (There have been some nice ones this year) but the problem I still have right now is that I just don't know when some of these events are going down. Unless I see a post here or an event listing from one of the facebook groups, I won't know an event is taking place until the last moment or after it has already happened. I'm sure there's not much that can be done about it but it just sucks to find out someone like Benga or Roska was playing the day (or month) after it happened.
The next step I'm hoping for an established weekly event (like Element's DnB Night). Hopefully having a weekly platform that promote not only international but also local DJ's & Producers can help grow the scene here. Hopefully beyond the "this is interesting" level it still seems to have to the locals here.
BTW, If it ever goes down and you need a DJ, let me know

.........If you're just looking for a DJ, Just let me know!
