Era & Context

Recorded in Los Angeles during the early 1970s rock-star-excess era, Vol. 4 mirrors its cocaine-fueled creation with a sound that swings between grandiose ambition and fragile beauty. The album arrived as progressive rock was reaching its commercial peak, and Sabbath absorbed some of that expansiveness while retaining their essential heaviness.
