1974's SABBATH BLOODY SABBATH is widely considered to be Black Sabbath's last true classic album. The musical experimentation that began on 1972's VOL. 4 was continued here, but this time it took the form of subtle synthesizer colorings (instead of VOL. 4's tranquil ballads). And whereas its predecessor didn't contain a true, instantly recognizable Sabbath anthem (save for "Snowblind"), SABBATH BLOODY SABBATH's title track resumed the quartet's penchant for penning heavy metal compositions that sounded like they were tailor made for being blasted in a huge arena.
