Off the Wall and Thriller. Then he kinda faded away. (Coincidentially, a crazy reclusive white pop star with the same name came out around that time.)
Anyway, I was listening to Thriller on vinyl the other day and that album totally stands up. "Wanna Be Startin' Somethin'" is a booty-shaker and in "Thriller", when Michael sings the title word ("cause this is Thriller...") it is the sweetest!
Damn, I miss that guy.
