Pepperland, the renowned evening-length work by Mark Morris, was originally created at the request of the City of Liverpool in May 2017, kicking off its Sgt. Pepper at 50 Festival, a season-long tribute to the groundbreaking Beatles’ album. Pepperland features an original score by composer Ethan Iverson inspired by the songs “Sgt. Pepper’s Lonely Hearts Club Band,” “With a Little Help from My Friends,” “A Day in the Life,” “When I’m Sixty-Four,” “Within You Without You” and “Penny Lane.”

An unprecedented chamber music ensemble of voice, theremin, soprano sax, trombone, piano, organ, harpsichord and percussion teases out and elaborates on Sgt. Pepper’s non-rock and roll influences. Arrangements of half a dozen songs from the album intermingle with Pepper-inspired original pieces intended especially for Morris’s profound understanding of classical forms: allegro, scherzo, adagio and the blues.
