It's sad but it's true, when an artists death occurs, they often become more famous post humously ( after they've died ), than the fame they experienced when they were alive.
Two that immediately come to mind for me are,
a. Stevie Ray Vaughn (Legendary Blues Guitarist)
b. Alice in Chains lead singer Layne Staley
Not until their deaths, and all the fanfare surrounding them did I come to realize how talented these artist were.
Who are some of yours? They could be actors, singers, muscians, rappers, and yes even painters.
Go ahead, Indulge me, please.
