The player is jazz Tubist Howard Johnson, who is well known for his solo work and his low brass jazz ensemble Gravity. If you are unfamiliar with Howard Johnson pick up one of his records. It will not be money wasted. I recommend Gravity on the Verve record label, which can be found at Amazon.com
Howard Johnson's music is essential for anyone who wants to try Tuba in a jazz setting. Whether you want to play tunes out of the real book or try out for a jazz band or combo, Howard Johnson's music is a great tool for young Tubists.
