The Historical Box - originally show at Hauser and Wirth Zurich but so damn good they brought it to London. Curated by Mara McCarthy of LA Gallery The Box, this is old school Los Angeles pioneers from 50s-70s. So many good artists - Stan VanDerBeek (its a VanDerBeek week with daughter Sara opening The Approach tonight), Barbara T Smith (her performances in particular were SO good), John Altoon. Conceptual without being dry. Funny without being flippant. This was a damn good show.
