72 is an important number for Metallica. It’s the age of both frontman James Hetfield and sticksman Lars Ulrich and it’s also the number of years since they last produced a decent album. It feels that way at least. But joking aside, 72 Seasons is a 77-minute behemoth (why didn’t they cut out one of the songs and make it 72?) and it seems like they’re finally back on the right track.
