"Liebermann was commissioned by the Stecher and Horowitz Foundation for an exam piece to be played by each contestant at the Eighth New York International Piano Competition, which took place in June, 2016 at the Manhattan School of Music in New York. The First Prize Winner, Aristo Sham, also won the award for Best Performance of Commissioned Work, so it fell to him to give the first public performance of the work. ""Mr. Liebermann, a fine pianist himself, writes some of the most idiomatic piano music today, so any contestant would be delighted to be assigned the Two Impromptus as a 'test piece.'” (Rorianne Schrade, New York Concert Review)"
