Ronnie Dio (1942-2010) was the legendary frontman of three of the best-selling, rock bands in history: Rainbow, Black Sabbath and Dio.
Mick Wall worked as Ronnie's London-based publicity agent after he joined Black Sabbath in 1980. And again, in the mid-90s, when Ronnie was fronting his own band, Dio. Mick also wrote about and interviewed Ronnie extensively as a journalist, TV and radio presenter from 1980 for 30 years. He is the author of Black Sabbath: Symptom of the Universe.
