[2] Originally based in Los Angeles, the art collective has expanded over the years with members across North American and Europe.
Members in Ultra-red range from artists, researchers and organizers from different social movements including the struggles of migration, anti-racism, participatory community development, anti-gentrification, and the politics of HIV/AIDS.
Other artists working in a similar vein include Chicago's Temporary Services, Berlin's Kein Collective and, in New York, LTTR.
In 2004, Ultra-red launched their own creative commons online label, Public Record, to showcase works of politically engaged ambient music.
[3] In addition to Ultra-red, other artists to appear on Public Record include Elliot Perkins (formerly "Phonem"), Sony Mao, Sebastian Meissner (aka Klimek) and The Soft Pink Truth.
