Black Sabbath is an iconic British rock band that pioneered heavy metal music in the late 1960s and early 1970s. Formed in Birmingham, England, the band consisted of members Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward. They're renowned for their dark, heavy sound characterised by Iommi's distinctive guitar riffs, Osbourne's haunting vocals, and themes often revolving around the occult, horror, and social issues.
Their self-titled debut album, released in 1970, is considered a landmark in the development of heavy metal, featuring classics like "Black Sabbath" and "N.I.B." The band's innovative style, blending bluesy tones with a heavier, darker edge, set the stage for countless metal acts that followed. Despite lineup changes over the years, Black Sabbath's influence remains profound, cementing their status as pioneers and legends in the world of rock and metal music.
