Phil Upchurch's albums
Jazz guitarist Phil UpchurchPhil UpchurchPhil Upchurch had no intention of playing on Off the Wall. He stopped by the studio just to say hello to Quincy JonesQuincy Jonesクインシー・ジョーンズ, who stuck a guitar in his hands and said 'play this one.' Upchurch ended up recording on 'Workin' Day and Night' and other tracks. For a veteran jazz guitarist with nearly 30 solo albums, this became his most widely heard work.
