This is one of the most “cult” experimental records in the entire history of jazz. Jo Jones, an immense drummer—a pioneering reformer with peerless technique—here gives us a complete demonstration of his art. Part 1 is devoted to drumming technique while Part 2 focuses on the great historical drummers in classical jazz. First released as two separate vinyl records in 1974, these titles were digitized, restored and reassembled in 2002 by Laurent Verdeaux, who also proposed extended versions. This is a vital set: it improves the quality of the listening-experience and increases the historic experimental value while enhancing the quality of the music. Drum-records, of course, but not just for drummers, whether they are amateurs or experts: this set is just as much for musicians, jazz fans, music historians and beat makers of all kinds.
