Techno-club-with-a-pop-room Potent turns five this weekend and they've got a bunch of big bookings, all from Berlin. Friday's headliner is Audrey Danza, co-founder of the label Proxima and resident at Motel Campo. She specializes in a kind of trance-inflected techno that is propulsive and melodic. Sounding good. She's joined by fellow Berlin-based DJ, Angioma, whose sound is also melodic but more on on the rave, acid techno, and breakbeat tip. Local support from Shanghai-based DJ, Stefano DVT.
