In the 1960s and 1970s, the annual Grand Gala du Disque was the awards ceremony during which the Edison Awards were presented to Dutch and international artists. These prestigious events were landmarks in the history of Dutch music broadcasting. On February 15, 1974, the astounding Canadian pianist Oscar Peterson and his trio of drummer Kenny Clarke and bassist Niels-Henning Ørsted Pedersen performed at the Grand Gala du Disque in RAI Amsterdam. They are soon after joined by eminent French-Italian violinist Stéphane Grappelli.
