The Chamber Music Society of Lincoln Center will perform Gregg’s chilling musical ghost story, The Tell-Tale Heart, on Halloween! This will be the Lincoln Center debut of Gregg’s music. Jennifer Johnson Cano, mezzo-soprano; Nicholas Canellakis, cello; pianist to be announced.

The world premiere of Gregg’s adaptation of Mary Shelley’s iconic novel, Frankenstein, will be produced in the 2023-24 season by Arizona Opera. Commissioned by Arizona Opera and funded in part by a gift from Linda and Stuart Nelson, Frankenstein will premiere with performances in Phoenix and Tucson. Arizona Opera’s President and General Director, Joseph Specter, said, “The timelessness of Shelley’s novel, combined with Gregg’s compelling score and libretto, will create an impactful opportunity for the opera art form to connect with both long-time devotees and newcomers alike… We believe this opera will become an important addition to the contemporary operatic canon.”

"Here [in Sketches from Frankenstein], as in The Tell-Tale Heart, Kallor achieved a perfect balance of text and music. The libretto hued quite closely to Mary Shelly’s original text, serving as a welcome reminder of her wonderful prose. Kallor’s music is a most interesting synthesis of elements of classical and jazz, galvanized into a singular compositional voice. There is plenty of heartfelt lyricism in his music, yet also enough complexity to keep it intriguing for those of us who seek more." –Arlo McKinnon, Opera News
