As per usual, the most interesting stuff happens at the Artscape fringes. The DJ Culture Takeover inhabits the Metro Gallery Friday and Saturday night with highlights ranging from excellent Baltimore house export Karizma to club classic Scottie B, dubstepper Joe Nice, funk maestros DJ Exclaime and Landis Expandis, awesome club goofball Jon Kwest, and much more. Also: air conditioning! High Zero’s future-music program Exotic Hypnotic returns once again, though now dubbed Worlds in Collusion due to some sort of copyright dispute, at the University of Baltimore Student Center. Check out Will Redman pushing the boundaries of classical music to improv magma and back again, the Baltimore Westsiders Marching Band, banjo innerspace traveller Nathan Bell and folk explorer Liz Downing’s Spaceships and Insects project, instrument inventor and craftsman Neil Feather, the Wrhatnala USA Gamelan Ensemble, and psych pummel from Horse Lords. Find also a light-show-plus-future-music performance from Andy Hayleck and Dan Conrad, Indian classical music from Soumya Chakraverty, and, yes, more air conditioning.
