Alice Cooper is known for his social and witty persona offstage. The Rolling Stone Album Guide going so far as to refer to him as the world's most "beloved heavy metal entertainer". Cooper helped to shape the sound and look of heavy metal, and the person who "first introduced horror imagery to rock'n'roll, and whose stagecraft and showmanship have enduringly misshapen the genre". Away from rock music, he is a film actor, a golfing celebrity, a restaurateur. Since 2004, Alice Cooper is a popular radio DJ with his classic rock show Nights with Alice Cooper.
