Rocky Hill, a founding member of ZZ Top and the brains behind the band’s 1983 hit “Legs,” has died. Radar Online reports that when he passed away last Friday, Rocky was estranged from his brother, current ZZ Top guitarist Dusty Hill. The two had a falling out after Rocky didn’t like Dusty’s wife and since then, Rocky began drinking heavily and got sick from cirrhosis of the liver. About three months ago, when Rocky was in bad shape, Dusty contacted him. While they never reunited face to face since their issues arose, as of press time, Dusty was expected to attend Rocky’s memorial service in Texas.
