Joshua Marquez is a Philadelphia-based Filipino-American composer, improviser, and sound artist whose music explores the liminal space between tone/noise and digital/analog as a means to investigate the complexities and duality of Asian American identity in search of connection during a diaspora. Searing a sonic imprint of cultural identity, his explorations of the noise spectrum represent alienation and assimilation through the fusion and fission of disparate timbres. Joshua’s music is described as “upsetting and calming in equal measure” with atmospheres that “sink into your skin” (Prism Reviews). Hailed as "cutting-edge" (The Gazette), “expertly crafted” (We Write About Music), "haunting" (The Daily Iowan), and "creepy" (Fanfare Magazine), Marquez's polemic deconstruction and disintegration of sound aims to present music through a decolonized lens.

Marquez's music has been performed and recorded, internationally, by ensembles and musicians such as the Arditti Quartet, JACK Quartet, Brno Philharmonic, Carmine Marcello Rizzi (violin), Iwona Glinka (flute), Akropolis Reed Quintet, Stony Brook Contemporary Chamber Players, University of Iowa Center for New Music, Gate City Camerata, Quintet Sirocco, Duo Charango, Bahué Duo, and the National Chamber Orchestra of Armenia, among others.

Never Ending Books (CT), the Spot Tavern (IN), RAIR (PA), Grounded Print Shop (PA), Nightlight (NC), Gravity Records (NC), the Wicked Witch (NC), All Data Lost Festival (NC), Elsewhere Museum (NC), and the Englert Theatre (IA), among others.

Joshua’s sound art has been installed at the Practice Gallery (PA), RAIR (PA) Gallery MC (NYC), Public Space One (IA), Becker Gallery (IA), Porch Gallery (IA), among others.
