Lauded by Opera News for her "rich, dark mezzo" and "... a voice so rich and colored that she easily steals any scene in which she appears" (Time Off), mezzo-soprano Jennifer Hines made her Metropolitan Opera debut in Moses und Aron with Maestro James Levine conducting. Since her debut she has maintained an active relationship with the celebrated company, participating in its Ring Cycle in the 2004-05 season. She made her recording debut in the title role of Astor Piazzola's Maria de Buenos Aires, Murry Sidlin conducting, recently released on the Koch label.

"But the surprise of the evening was mezzo-soprano Jennifer Hines, who has a voice that has to be heard to be believed. Few mezzos display such a timbre. If you closed your eyes, you would swear that her lines were being delivered by a true countertenor. It was remarkable. Not to demean the other singers in any way, but it is worth the price of admission just to hear her." - [Verdi's Requiem, Richmond Symphony] - Walt Amacker, Richmond Times Dispatch (03/16/08)

"The dark, rich, buttery tones of mezzo-soprano Jennifer Hines were an unending astonishment." - Mark J. Estren, Washington Post (12/10/07)

"Backed by the heavenly choir, mezzo Jennifer Hines made the ending 'Agnus Dei' special, her dusky, contralto-like voice wrapped around phrases like an Earth Mother's embrace." [Rossini's PETITE MESSE SOLENNELLE - Michael O'Neal Singers]
— Pierre Ruhe, Atlanta Journal-Constitution

"Jennifer Hines - pint-sized and stunning with a rich, powerhouse contralto - is the find of the season." [DAS RHEINGOLD - Washington National Opera]
