Era & Context

By further detuning their instruments, Black Sabbath pushed heaviness into territory that wouldn't be fully explored for another two decades. Released as hard rock bands competed for virtuosity, Master of Reality chose simplicity and weight, anticipating doom metal and stoner rock by creating a gravitational center that slower, heavier bands would orbit for decades.
