Described as “an African Bartók,” Justinian was trained in both Kiganda (Ugandan) folk music and Western classical music, receiving his doctoral degree in composition at Northwestern University. He will compose several new pieces for Orchestra 2001’s musicians, using extended instrumental techniques, microtones, and polyrhythms that marry contemporary classical music and traditional Kiganda folk music.

GEORGE CRUMB: SCORES AT AN EXHIBITION will explore Philadelphia’s well-known contemporary composer (1929-2022) and long-time Orchestra 2001 collaborator, in a visual arts setting. His stunning visual scores are works of art, and presenting them in a gallery context allows for a more complete appreciation of these masterpieces.

Exhibits of Crumb’s scores will be followed by performances of several of his chamber music works at Slought, Esperanza Arts, and Cherry Street Pier.  Crumb’s brilliant “Metamorphoses, 10 Fantasies for Amplified Piano, Book 2” (2020) will be performed by the musician he wrote it for, Orchestra 2001 pianist Marcantonio Barone, presented with images of the works of art that influenced Crumb’s modern take on “Pictures at an Exhibition.”
