The artist Sara Roberts and Machine Project invite the public out for two participatory group art performances.
From the event website:
Clump is an experiment in group/crowd behavior, based on a simple rule set but without fixed outcome or direction. In Whistle the crowd, equipped with multi-pitched whistles, configures to play compositions based on what the person next to you has just done, making propagating sound waves.There will be two open rehearsals for the event; check the website for details. The event is presented as part of Machine Project's Field Guide to L.A. Architecture.
