Liebermann began studying piano at the age of eight. His first published work was a piano sonata, which he introduced at Carnegie Recital Hall just months after his sixteenth birthday. Later he studied composition with David Diamond and Vincent Persichetti at the Juilliard School. He has been composer-in-residence with the Dallas Symphony Orchestra, the Saratoga Performing Arts Center, and the Pacific Music Festival. He joined the composition faculty of Mannes College in 2012, and the following year was appointed head of its composition department. He was the first recipient of the Virgil Thomson Award in 2014, and lives in Weehawken, New Jersey.
Liebermann has written over one hundred thirty works in all kinds of genres. He has written works for Paul Zukovsky, Paula Robison, Gerald Schwarz, Stephen Hough, Mstislav Rostropovich, and James Galway, among others, as well as an opera based on Oscar Wilde’s The Picture of Dorian Gray. His music was used at the 2001 Van Cliburn Competition.
Liebermann has written concertos for cello, clarinet, flute, piano, trumpet, and violin. The Piccolo Concerto was commissioned by the National Flute Association and first performed on August 18th, 1996, at the National Flute Association Convention in New York City. The soloist was Jan Gippo (to whom the work is dedicated); Glenn Cortese conducted the New Jersey Symphony.
