His North American opera engagements include the Metropolitan Opera (Moses und Aron, Wozzeck, La traviata, Sly, Die Fledermaus, Romeo et Juliette, Lucia, Madama Butterfly), and title roles for over a decade at the New York City Opera, notably as the Count in Le nozze di Figaro in a Live from Lincoln Center telecast and the title role in new productions of Hindemith's Mathis der Maler, and Busoni's Doktor Faust.
As a concert artist, Stone has appeared with every major orchestra in the country, including the New York Philharmonic under Kurt Masur and the Boston Symphony Orchestra with Seiji Ozawa conducting the premieres of Takemitsu's My Way of Life, and Kirchner's Of Things Exactly as They Are. His long relationship with Robert Shaw resulted in acclaimed performances of the monumental choral works and over a dozen recordings, including the two Grammy Award recordings of Hindemith's When Lilacs Last in the Dooryard Bloom'd, and Walton's, Belshazaar's Feast, and an Historic Live Performance Edition of Ein Deutches Requiem with the Cleveland Orchestra . Other recordings include The Songs and Arias of Robert Ward, and DVDs of Carnegie Hall's Performance Series of Hindemith's When Lilacs Last in the Dooryard Bloom'd, and Verdi's Falstaff with Jose van Dam.
Equally at home on the recital stage, Stone considers his many performances of Wolf's Italienisches Liederbuch with Benita Valente and David Golub among the most memorable. In addition to his performing career, Mr. Stone is Professor Emeritus of Voice and Opera at Temple University, and currently is teaching on the Voice Faculty at the Academy of Vocal Arts in Philadelphia.
