The Underground Producers Alliance (UPA) is a creative think tank of renowned professional artists, producers, performers, and engineers, committed to the global development of innovative and experimental artistry, through master class seminars, workshops, recording sessions, installations, archival restoration, developing new technologies, live performances and curated events.

Founded by Ghost Producer (Badawi, Sub Dub, Raz Mesinai), Scotty Hard (Wu Tang Clan, Vernon Reed, Brownsville KA), and Honeychild Coleman (the 1865, The Slits), with Juma Sultan (Jimi Hendrix, Richie Havens, Aboriginal Music Society), Prince Paul (Gravediggaz, De La Soul, Jungle Brothers), HPrizm aka High Priest (Anti Pop Consortium), Juma Sultan (Jimi Hendrix, Aboriginal Music Society) and Max Glazer (Rihanna, Sean Paul, Federation Sound) and others joining soon after, the UPA has become the premier artist development agency and education program focused on the preservation and continued study of experimentalism in sound, music, and art in both New York City and abroad.

In 2010, with the permission of Juma Sultan, the Underground Producers Alliance began production on the restoration of the Studio We archives, currently known to be the largest archive of Avant/free jazz and experimental music from the loft jazz era in existence, with over 2000 hours of audio material, hundreds of rare photographs, scores, fliers and archival footage from concerts throughout the 5 boroughs of NYC during the 1960s and 1970s, and includes rare material by Milford Graves, Pharoah Sanders, Sun Ra, Sam Rivers, Sonny Simmons, Archie Shepp, Kalaparusha and hundreds more.
