The music of composer Steve Antosca focuses on the integration of instruments with computers for audio processing and spatialization. Through the realization of scores that combine elements of indeterminacy and traditional notation with technology, musicians craft sonically rich performance environments. The Washington Post has described his work as “spectacular, wonderfully provocative” and “a shimmering, multilayered sea of sound, surging with power under a surface of delicate detail — a fascinating dance between the human players and their electronic ghosts.”

Named Artistic Director of the National Gallery of Art New Music Ensemble (NGA NME), which he formed in 2010, Antosca was the Gallery’s composer-in-residence in the Fall of 2013. His compositions for the NGA NME blend the architectural resonances of the Gallery’s unique performance spaces with computer treatment of performers' sounds to generate a rich fusion of sonic textures.

Antosca has received awards and commissions from the American Composers Forum/Argosy Foundation Contemporary Music Fund, Bourges International Competitions, Chamber Music America and Pictures on Silence, DC Commission on the Arts, Fromm Music Foundation at Harvard University, Georgetown University, International Music Prize for Excellence in Composition from the National Academy of Music, Johansen International Competition, Kennedy Center, Maryland State Arts Council, McKim Fund in the Library of Congress, Meet the Composer, National Endowment for the Arts, No Exit Ensemble, Randy Hostetler LivingRoom Music Fund, and the US Department of Education. Antosca has a master’s degree in computer music composition from the Peabody Conservatory of Johns Hopkins University.

From 2002 through 2012, Antosca was Artistic Director and composer member of the highly regarded VERGE ensemble, in residence at the Corcoran Gallery of Art. The Washington Post wrote, the ensemble places modern classical music in front of the public with more dedication and skill than any other group in Washington” and is “a national presence.

Antosca was a co-director of the 2012 John Cage Centennial Festival Washington, DC, which took place throughout the Washington area September 4 – 10, 2012. Regarding the Festival’s impact, the Washington Post wrote that for Washington where artistic life centers on museums and conservation” the Festival “could be seen as a gradual shift in Washington where Antosca, the National Gallery, the Library of Congress, the Maison Francaise and others have been working hard to cultivate a contemporary music audience.”
