Hard to believe perhaps, but the elevated street, pop surrealist and urban art emporium Thinkspace has been banging it out for 15 years. In that time they've evolved from an indie outpost to a global curatorial and muralizing force, but in the spirit of not forgetting where they started, they're getting more than 70 members of its extended artist family together to celebrate the milestone. With everyone working on 15x15-inch panels (courtesy of Trekell), artists as stylistically diverse as Andrew Hem, Bumblebeelovesyou, Mark Dean Veca, Carlos Ramirez, Casey Weldon, Dalek, Meggs, Nosego, Perez Bros., Stella Im Hultberg, Seth Armstrong, and more all contribute to the massive group show and party that is 15 Years of Thinkspace.

Thinkspace, 6009 Washington Blvd., Culver City; opening reception: Sat. Jan. 11, 6-9 p.m.; exhibition through Jan. 25; free. thinkspaceprojects.com.
