Atheist + Revocation + A Life Once Lost + A Last Chance to Reason

As evidenced by a rousing new Motörhead album and matching documentary, metal’s meat-and-potatoes old guard remains firmly entrenched. Fortunately, the genre’s thriving underground is expansive enough to accommodate any number of off-the-grid eccentrics. One of the best is Florida’s Atheist, whose phantasmagoric creations—like classicist thrash gone Hieronymus Bosch—have only grown stranger with age: The band’s 2010 reunion effort, Jupiter, actually topped its fusion-informed late-’80s/early-’90s releases for sheer frenetic flamboyance, somehow upping the catchiness factor at the same time.
