2007 ~ for violin and real-time computer processing

“… when the bud unfolds and from the lesser the greater emerges, then One becomes Two and the greater figure, which one always was but which remained invisible, appears with the force of a revelation.”  -  Carl Jung

One becomes Two, premiered by violinist Lina Bahn at the Phillips Collection in Washington, DC in March 2007, was described by the Washington Post as “the afternoon's most exciting composition. It was performed with knowing sensitivity by Bahn, her violin plugged into Antosca's laptop, her fiddle generating ambient electronically controlled responses that were repeated or transformed into vaporous, liquid reflections of her sound.” One becomes Two received its European premiere in Paris by Ms. Bahn at the Festival de musique Américaine in May 2007 and has been performed throughout the US and in China.

One becomes Two was a selected winner in the "Electroacoustic music with instruments" category of the 36th Bourges International Competitions 2009, and was performed in November 2009 at the International ElectroAcoustic Music Festival 2009 in Rome and at the inaugural concert of the National Gallery of Art new music ensemble in the Atrium of I. M. Pei’s East Building of the National Gallery on March 7, 2010 at the CHANGES:seasons concert.

A graphic page from the score for One becomes Two was published in Notations 21, a modern day compendium and anthology of illustrated contemporary scores in the style of John Cage’s 1968 book Notations.
