If you like your art on the more (inter)active side, chances are you'll dig The Least Important Things, a showing by LA-based artist Emily Mast that is basically a sequence of free-standing vignettes (based on a diverse range of works by Catalan artist Joan Brossa) scattered throughout LACMA's campus. Audience members will be offered hints and clues to direct their experience of the pieces. Think of it as part exhibition, part scavenger hunt. Start at the Los Angeles Times Central Court at 8pm, and make sure to wear comfortable shoes and warm clothes; some of the clues require walking, being outside, and climbing up stairs. Tickets are available for pick-up at the ticket office one hour before the performance.
