During one of their last concerts in 1967 which remained unreleased until then, the Dave Brubeck Quartet, comprising more or less the same members since it's inception, had already been playing for 16 years. Naturally, they were more than well acquainted. Dave and Paul made their debut at the Black Hawk Night Club in San Francisco. Their hallmark: relentless combatting racial barriers, even in the darkest periods of McCarthyism, and making jazz accessible to the widest possible public by revisiting ballads, old favorites and well-known classical themes. But above all, they developed an almost endless variety of complex time signatures. That evening of 24 October 1967 in Scheveningen, the Dave Brubeck Quartet was not a band playing jazz. They were the worthy ambassadors of American music in Europe.
