Elkana continued his studies at Bard College, New York City where he earned an MFA in Music and Sound.

At Bard he focused on electronic music and took lessons with Pauline Oliveros, David Behrman, Richard Teitelbaum, George Lewis, Maryanne Amacher, Larry Polansky and more.

In its review of Arabic Lessons, the Jerusalem Post called it "a perplexing, beguiling 40-minute opus in which the composer challenges the so-called 'acceptable' form of the lieder, shattering it and building it anew, as if constructing a new world from its ashes.

Elkana’s short opera "The Journey Home" comments on the Israeli-Palestinian conflict by telling the true and incredibly touching story of a Palestinian man who lived in this troubled land during most of the 20th century.

In 2013-2014 Elkana was invited to be a fellow for a year at the International Research Center »Interweaving Performance Cultures« in Berlin where he worked on his next opera "Nathan the Wise".

The original text was edited into a libretto in Hebrew, German and Arabic by Elkana's long time collaborator Michael Roes while preserving Lessing's unique poetic language.

"Casino Umbro" is the title of Elkana's recent CD released to great critical acclaim on the American label Ravello in 2012.

In 2010 he opened the International Literature Festival in Berlin giving a concert of his music for Recorded voices of poets, Electric guitar and electronics.
