musica orbis

"Back in the Air" was a concert first presented at University of Pennsylvania's Zellerbach Theater at the Annenberg Center, in September of 1975. Below is a poster for the New York City performance on October 9, 1975, at WBAI-FM's FREE MUSIC STORE. It was Musica Orbis's way that most of the concert's repertoire was composed and prepared uniquely for "Back in the Air."
