Ultra-red is an international sound art collective founded in 1994 by two Los Angeles AIDS activists. The collective's current twelve members work as organizers and educators with community-based organizations and social justice movements in Germany, the UK, and the United States. Utilizing a practice the collective calls, "militant sound research," Ultra-red investigations unfold slowly over time wherein sound and listening serves as the medium and as a site of inquiry. In 2012 the Los Angeles members of Ultra-red launched School of Echoes Los Angeles, an experiment in popular education mentorship with students, artists, and community organizers. That group was instrumental in founding the L.A. Tenants Union in 2015, now a citywide movement with six neighborhood chapters and dozens of community activists fighting gentrification and mass displacement across Los Angeles.
