Black Sabbath was an English heavy metal band from Aston (Birmingham), existing under this name from 1969, which is considered to be the co-founder of this genre and a defining force in hard rock in the early 1970s. The band is said to have had a significant influence on the development of rock and heavy metal music in the decades that followed, as well as on the emergence of the subgenre of doom metal and indirectly on black metal through its sometimes diabolical content. Their last concert took place on February 4, 2017 in their hometown of Birmingham. (Source: Wikipedia.de)
