Shanghai's crew for underground techno and house were there on the night Shelter opened. They've kept their monthly night going for seven years - that's a feat in this revolving-door city. In their words, "Void has also battled manfully to defend the people's right to dance to the highest-quality electronic music, free from misleading hype, corporate sponsorship bollocks and false prophets." Here's a live recording of the birthday set from last year. The anniversary party features sets by Shanghai Ultra, Chris Jobs, Wensen, and Ginzburg. Starts at 10pm, cover is 30rmb. Limited-edition VOID T-shirts on sale as well.
