During one of their last concerts in 1967 which remained unreleased until then, the Dave Brubeck Quartet, comprising more or less the samemembers since its inception, had already been playing for 16 years. Naturally, they were more than well acquainted. Dave and Paul made their debutat the Black Hawk Night Club in San Francisco. Their hallmark: relentless combatting racial barriers, even in the darkest periods of McCarthyism, andmaking jazz accessible to the widest possible public by revisiting ballads, old favourites and well-known classical themes. But above all, theydeveloped 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 ofAmerican music in Europe.
