I did a search and I was very surprised that i didnt find a post for W.S. Holland (Johnny Cash's Drummer). He was a great rockabilly and country drummer. I play in a Cash tribute band and I think he helped define the rockabilly and outlaw country drum sound.
His train doubles on Orange Blossom Special are outstanding. His ability to groove with a rockabilly shuffle on both the ride or hats as well as the snare at the same time is outstanding. A very full sound.
