Edgard Varèse conducts a workshop with jazzmen Art Farmer (trumpet), Hal McKusik (clarinet, alto sax), Teo Macero (tenor sax), Eddie Bert (trombone), Frank Rehak (trombone), Don Butterfield (tuba), Hall Overton (piano), Charlie Mingus (bass), Ed Shaughnessy (drums), probably John La Porta (alto sax)... We don't know who is on vibes...
It might be the first free jazz recording (totally unissued) of History of Music. Varèse might have influenced jazzmen or was he only aware of what was happening on the jazz scene? No matter of the answer, it's a bomb, as this music is 3 years earlier than Free Jazz by Ornette Coleman! We also know Charlie Parker wanted to study with Varèse in autumn 1954 but the composer flew to Europe to conduct Déserts. When he came back to New York in May 1955, Parker had already died. We also know that Varèse used to listen to John Coltrane at the Village.
Between March and August 1957, these Sunday jam-sessions were followed by arranger George Handy, journalist Robert Reisner, composers James Tenney, Earle Brown and John Cage, choreographer Merce Cunningham. The organizers were Earle Brown and Teo Macero who will become Miles Davis' producer among others. Varèse used certain extracts of the workshop for his Poème électronique.
