This is also easy. Marley in a big way. Marley was an original, until the day he died. Cash was an original, for the first decade or so his career, then he was pretty much a cover artist (taste-monger) his final few decades. Not that I'm dissing Cash, but I'm not going to give him the grandpa treatment everyone else does. Just wait until the pulp culture puts Willie Nelson on its shoulders and runs him around the field.
