Metallica's '72 Seasons': A Deep and Hard-Hitting Album with Lengthy Tracks.

Metallica's 12th full-length album, "72 Seasons," explores the cruelty of youth and the dangers of growing up. The album combines youthful fury and adult wisdom, with more than 40 years of experience, the band plays with more purpose than in their speed-demon days. The tracks show an alpha male breaking the facade of brash metal rage as he searches for his own truth. The album is a master class in melancholy and features Metallica's longest-ever song, "Inamorata."
