The central instrument is the Syn-Ket, a small portable polyphonic synthesizer built in 1965 by Paolo Ketoff in Rome, designed for live performance rather than studio tape work. John Eaton, an Indiana University composer who had spent time in Rome on a Prix de Rome and a Fulbright, built much of his work around it. Fewer than a dozen Syn-Kets were ever made (Sun Ra owned one, Stockhausen another).

Mass (1970), commissioned by the Koussevitzky Foundation, is the centrepiece: three Syn-Kets, a Moog (Jay Williams), Mini-Vox and Syn-Mill (Andrew Jarema), the Japanese soprano Michiko Hirayama (later Giacinto Scelsi's principal vocal interpreter) and the clarinettist William O. Smith, who plays multiphonics and double-stops. John Reeves White conducts. Blind Man's Cry (1968) is a smaller setting. Concert Music for Solo Clarinet closes.
