Here's one of Joey DeFrancesco playing the blues a few year ago. DeFrancesco adopted the jazz organ at a time when it was in a bit of a lull in the jazz community during the late 1980s, when the jazz community more or less saw the gradual expiration of many established players and a reluctance of younger generations to adopt the instrument. Joey revived the organ by adopting some of the best aspects of the instrument's lengthy and illustrious past, and even though he is not the most innovative player himself, he had a huge ability to organize and retain the great innovations of previous artists before him. This gave the instrument a much needed shot in the arm it still enjoys today. Let's hope Joey also takes care of his weight soon, he's way too young to leave the jazz world.
