The early 70s saw a turbulent changing of the cultural guard.

The deaths of Shostakovich, Louis Armstrong, Jimi Hendrix and Janis Joplin and the disbanding of the Beatles was set against Miles Davis’ jazz/rock fusion revolution and the birth of heavy metal (Black Sabbath) and techno (Kraftwerk).

Music was moving in a million directions at once, like in Joe Zawinul’s In a Silent Way (made famous by Miles Davis) and André Jolivet’s quixotic Heptade, performed here by Constable and Principal Trumpet David Elton.
