Jack Skurnick, director of EMS Recordings, produced early post-war recordings of Varèse; this piece appears on the first Varèse LP, EMS 401: Complete Works of Edgar Varèse, Volume 1. "Ionisation" had also been the first work by Varèse to be recorded in the 1930s, conducted by Nicolas Slonimsky and issued on 78rpm Columbia 4095M. The players for the recording included, in addition to the composer himself on the sirens, Carlos Salzedo on Chinese blocks, Paul Creston on anvils, Wallingford Riegger on guiro, Henry Cowell on piano, and William Schuman on the lion's roar.
