While some older archives occasionally list this interview as occurring in 1960, the Max Neuhaus Estate and contemporary researchers confirm the date as December 20, 1963. At this time, Corigliano was active in the New York avant-garde radio scene before his own rise to fame as a Pulitzer-winning composer.
John Corigliano, the music director of WBAI interviews percussionist Max Neuhaus about his work interpreting and performing Karlheinz Stockhausen's work Zyklus. Although Stockhausen originally intended the piece to be played spontaneously, most percussionist found that the range of instruments the piece called for, (twenty one) to be too unwieldy to make a spontaneous performance possible. However after consulting with Stockhausen and spending months practicing Neuhaus finally managed to perform the piece satisfactorily.
