Stump Juice  Stump Juice is an album by American jazz organist Jimmy McGriff recorded in 1975 and released on the Groove Merchant label. Allmusic's Jason Ankeny said: "'Unlike the majority of Groove Merchant dates from the mid-'70s, "Stump Juice" forgoes warhorse pop and soul covers in favor of original tunes – these tabulas rasa are the ideal canvas for Lester's bare-essentials production and McGriff's sinuous grooves, eschewing fusion and disco influences in favor of raw, unadulterated jazz-funk".
