There are as many flavours of jazz as there are pebbles on a beach, but the majority combine rhythmic invention with instrumental virtuosity to create a sound that can transport the listener to a different plane. Whether your ear is caught by the saxophone of Earl Bostic or Eddie Harris, the flute of Herbie Mann, Ray Charles' effervescent keyboards (he played sax too) or the music of Cuban born 'King of the Mambo' Perez Prado, whose 1958 US chart-topper 'Patricia' is familiar from countless movies and television ads, one thing is certain - the jazz instrumental still reigns supreme.
