Black Sabbath, an English based band, are generally regarded as the grandfathers of modern metal. Originally formed in 1968 as a blues rock band, the group soon adopted the Black Sabbath moniker and began incorporating occult themes with horror-inspired lyrics and tuned-down guitars. Despite an association with these two themes, Black Sabbath also composed songs dealing with social instability, political corruption, the dangers of drug abuse and apocalyptic prophecies of the horrors of war. They continued to record and tour through 2010-2020 thrilling audiences everywhere they played.
