Released in 1971 by RCA Victor, it features Oxley on percussion, Evan Parker on saxophone, Kenny Wheeler on trumpet and flugelhorn, Paul Rutherford on trombone, Derek Bailey on electric guitar, and Barry Guy on double bass.

[1][2][3] In a review for Paris Transatlantic, Graham L. Rogers wrote: "This is powerful work from a time and place when free improvisation was in its youth and talented musicians with uncluttered heads took risks and disregarded rules, creating the spontaneous, imaginative music which came to define the genre.

"[6] Author Ben Watson stated: "By seizing the timbral serialism of Webern and performing it with the expressive velocity of jazz, Oxley's group heralded almost everything new in music for the next three decades...

It revives Edgard Varèse's project of a music that would organise itself according to the dictates of timbre and the impact of noise rather than overarching systems of harmony and rhythm.

Monumental, intricate, detailed and balanced music and just a classic album of the highest beauty!"
