Abby Powell was born in Ohio in 1980 and studied voice at The Juilliard School of Music in New York. While there she was awarded the Rise Stevens Award, the G. & M. Grunin Prize, and the Loretta Lewis Award in Voice, among others.

In 2000 she made her operatic debut as Zita (Puccini's Gianni Schicchi) and shortly after that was cast as Ma Moss (Aaron Copland's The TenderLand) at Aspen Opera Theater (Aspen Summer Music Festival and School) and The Juilliard Workshop, respectively.

The following year she returned to the Aspen Summer Music Festival to perform Brahms' Opus 91, Zwei Gesange fur Alt und Viola alongside the auspices of Masao Kawasaki, viola, and Orli Shaham, piano. The performance won her much acclaim – it was followed by an invitation to perform in Taiwan, as well as numerous opportunities in New York.

In 2002, Ms. Powell was cast as Britten's haunting Miss Jessel (The Turn of the Screw) and the opera subsequently haunted her – she spent the following year recreating the role in venues across America.

Ms. Powell has sung under the batons of James Conlon, Julius Rudel, Harry Bickett, Steven Osgood, and Miguel Harth-Bedoya, to name a few. Her operatic roles have included Juno (John Eccles' Semele), both Dido and The Sorceress (Purcell's Dido and Aeneas), Mere Marie (Poulenc's Dialogues des Carmelites), Lyubasha (Rimsky-Korsakoff's The Tsar's Bride), Marcellina (Mozart's Le Nozze di Figaro), Charlotte (Werther's Massenet), and many others.

She is a student of W. Stephen Smith.
