boston dnb messageboard at http://elements-dnb.com/bb/. for other event listing junk see http://weeklydig.com and http://thephoenix.com. if you're going to be there a couple nights, the best and longest-running dnb thing in boston is a weekly over the river in cambridge on thursdays--called elements, at a bar called phoenix landing. even if the selection happens not to be your style, the venue, sound system, massive beer selection, and crowd are all great. it was my thursday night for three years.
Damn man, you got here Tuesday? that means you missed Paradox by 1 night!! (was monday night).
Elements is great, even if it's mostly more "normal" dnb stuff it doesn't have any shit new dnb attitude, all sorts of people getting down from sketchy ravers to MIT geeks & Kurzweil engineers. I don't go to it nearly as much as I should anymore, but it's always a good time.
Beat Research is every monday night across from elements, not dnb but a variety of cool "Deep" stuff. www.beat-research.com
not sure what's going on this weekend, I'm playing a show out in Lowell on Friday but that's a bit of a pain to get to (think I'm getting a ride from the promoter) and it's much more of a hardcore/noise/whatever show.
Maybe check out the Trainspotters shop, they should know what else is up.
