Co-founders Mario Ybarra, Jr. and Karla Diaz left this fair city for ARCO2010 in Madrid. They have an installation and performance called Police and Thieves as part of Invisible Cities, curated by Kris Kuramitsu and Christopher Miles, at the Instituto Cervantes. This installation, named after Junior Murvin's song "Police and Thieves," features the struggle between cops and robbers from both sides of Los Angeles' mean streets and displays all sorts of LAPD and bad guy sundries -- from LAPD complaint forms to prison ink drawings to beloved shanks. Ybarra and Diaz's performance will follow the panel discussion on the 19th. If you happen to be in Madrid, get your dose of Slanguage in España!
