Recently went to this dive in Cambridge for a drum and bass night. The music was earsplitting and barely music. I think a 12 year old on GarageBand could make better music. (To really understand, youtube drum and bass.)
The Phoenix Landing is down the street from The Middle East in Central Square.
Music (loud random noises) aside, The Phoenix Landing was a bizarre crew. A awkward mix of hippie/ "alternative" types were tripping out and made the place a general hazard zone. Drinks were not expensive and the bartenders were quick, but it was hardly a scene conducive to a good time.
My advice, stick to the Middle East. Angst-y Berklee bands and amateur DJ's are definitely a better time.
