"Richard Groove Holmes - Soul Mist! -1966 US":

Richard Arnold "Groove" Holmes (Camden, New Jersey, May 2, 1931 – St. Louis, Missouri, June 29, 1991) was an American jazz organist who performed in the hard bop and soul jazz genre.
A standards-heavy date, 1966's "Soul Mist" is one of Richard "Groove" Holmes' most relaxed and swinging discs. Exploring the higher registers of the Hammond B3 instead of the familiar funky bass sound, Holmes' playing actually resembles the electric organ version of Dave Brubeck's familiar melodic piano sound, although the lightfooted cover of "Autumn Leaves" owes a lot to Bill Evans' readings of the tune.
