Metallica has unveiled the title track of its forthcoming 12th studio album, 72 Seasons. A seven-and-a-half-minute opus that opens the new record, “72 Seasons” is the fourth advance offering from its namesake—following the recent release of the “epic” (Rolling Stone) “If Darkness Had A Son,” hailed by Consequence as “a sonic retrospective of (Metallica’s) career,” as well as the “scorching” (Guitar World) “Screaming Suicide” and “thundering, breakneck” (Billboard) first single “Lux Æterna.”
