Countertenor Jeffrey Mandelbaum made his debut at the Metropolitan Opera in The Enchanted Island singing the role of Ferdinand alongside Joyce DiDonato, conducted by William Christie. He was hailed as a "first-class countertenor" by the Washington Post, and returned to the MET for The Tempest, and the revival of The Enchanted Island. He sang Xmas Oratorio and Magnificat at Alice Tully Hall, and made his Carnegie Hall debut singing Chichester Psalms for the Centenary of Leonard Bernstein. 

Opera News has stated, “Jeffrey Mandelbaum, with a sweet sound, was highly satisfying and brought considerable flair to his singing and characterization.” He performed in Monk’s Quarry at the Spoleto Festival (USA), and was engaged by New York City Opera for Flavio, Ulisse, and Hansel and Gretel, as well as the Brooklyn Academy of Music for Glass’s Galileo Galilei. 

He is a winner of the 2003 Metropolitan Opera National Council Auditions, New York Districts. He attended Oberlin and Mannes, coached in baroque style with Drew Minter and Julianne Baird, and studies vocal technique and artistry with Linda Monssen. 

Mr. Mandelbaum founded Opera Essentia last year, and is excited to continue curating Handel’s neglected operas, and presenting them in accessible performances.
