“The text of WICBM refers to a historical event with radio's Emergency Broadcast System (EBS), the U.S. government’s means of warning the country of imminent nuclear attack during the Cold War era. The North American Air Defense Headquarters in Colorado, an operation of the Air Force, conducted tests with the EBS regularly on Saturday mornings at 9:33 a.m., Eastern Standard Time. On February 20th, 1971 however, the Air Force had “run the incorrect tape,” causing mass panic and confusion for nearly half an hour. WICBM consists of symmetrical chords that emanate from a whole step above middle C. These chords fuse with a high degree of harmonicity (or smoothness) when tuned purely, that is, in just intonation (JI). Thus, WICBM uses the common performance practice of barbershop harmony, an intuitive process by which performers adjust pitches microtonally up or down in order to strike a super concordant effect."-Toby TwiningWorld Premiere by Young People’s Chorus of New York City and Francisco J.
