Griffelkin is an opera by Lukas Foss with a libretto by Alastair Reid. The opera was first performed on November 6, 1955, in a nationwide telecast by the NBC Opera Theatre. Following the success of Gian Carlo Menotti's Amahl and the Night Visitors, NBC decided to present new operas by other American composers and gave Foss a commission for the work. (Other composers involved in the project included Norman Dello Joio, Stanley Hollingsworth, and Leonard Kastle.)
These performances of Griffelkin are a co-production with Pittsburgh's Creative and Performing Arts (CAPA) magnet school's Opera Workshop.
