BLACK SABBATH
Four for Eternity: Sabbath's "Vol. 4."
"Vol. 4" is perhaps the most underrated album of Black Sabbath by the music interested public. Fans and connoisseurs see it differently, however, because the LP with the low association title is one of the most important in the career of the band that is so decisive for the history of hard rock. The fact that the album was released in September 1972 still borders on a miracle in view of the massive cocaine consumption of the band.
