BLACK SABBATH

Black Sabbath were an English heavy metal band formed in Birmingham in 1968 by guitarist Tony Iommi, drummer Bill Ward, bassist Geezer Butler and vocalist Ozzy Osbourne. After adopting the Black Sabbath name in 1969 (the band were previously named Polka Tulk Blues Band and then Earth), they distinguished themselves through occult themes with horror-inspired lyrics and down-tuned guitars. Their first three albums, Black Sabbath, Paranoid (both 1970), and Master of Reality (1971), were commercially successful, and are cited as pioneering albums in the development of heavy metal. Subsequent albums Vol. 4 (1972), Sabbath Bloody Sabbath (1973), Sabotage (1975), Technical Ecstasy (1976), and Never Say Die! (1978) saw the band explore more experimental and progressive styles. Osbourne was fired from Black Sabbath in 1979 and replaced by former Rainbow vocalist Ronnie James Dio, who recorded three albums with the band, Heaven and Hell (1980), Mob Rules (1981), and their first authorised live album Live Evil (1983), the last two featuring drummer Vinny Appice replacing Ward. Following Dio and Appice's departures, Iommi and Butler recorded Born Again (1983) with Ward returning on drums, and Ian Gillan, then-formerly of Deep Purple, on vocals.
