For two decades, the highly successful and respected contemporary jazz quartet known as Fourplay has enjoyed consistent artistic and commercial success by grafting elements of R&B, pop and a variety of other sounds to their unwavering jazz foundations. In the course of a dozen recordings – six of which have climbed to the top of Billboard’s Contemporary Jazz Album charts – the supergroup has continued to explore the limitless dimensions and permutations of jazz while at the same time appealing to a broad mainstream audience. Since 1990, bassist Nathan East, keyboardist Bob James, guitarist Chuck Loeb (who joined five years ago) and drummer Harvey Mason have continued to explore together.
