Jimmy Smith
The Late Larry Young(From Newark, New Jersey,his best cds are Unity or
The Art of Larry Young, he really plays some interesting tonalities and chords).
John Patton
Jimmy McGriff
Charles Earland
Don Patterson
Joey DeFrancesco
Red Young(local guy in Dallas/Austin, has incredible pedal chops, has played with some big people, unfortunately none of his recordings showcase his unique talent).
Anyone that plays good gospel organ. I don't know all their names.
That guy that plays with Marvin Sapp and Kevin Bond is great.
