Ever mucked about on the Potrero Del Sol Park playground? You know, the skateboarder-y Dolores alternative with the multi-person swing and diagonal spinning chair of happiness? If not, learn yourself. If so, you might have noticed a wad of crummy tin-roofed warehouses stuffed under the 101. 

One of those warehouses, goforaloop Gallery, has arranged a free masquerade party on Saturday night. Performances include wiry LA rock'n'rollers Queen Caveat, and ~wait what~, a mash-up DJ whose subtlety will shatter the awful impression you've gotten from the brazen tossers who play at Bootie. The kid also produced the B.I.G./London art rock mixup album The Notorious xx. 

Behold their Lil Jon en-crunked event page.
