Jack Sabbath Is the Heavy Metal Daycare Supergroup You Didn't Know You Needed
Jack Black joined forces with original Black Sabbath legend Geezer Butler and a crew of rock stars' talented kids for a wild, cross-generational jam session.

The Ultimate School of Rock Moment
If you ever wondered what would happen if Jack Black decided to form a heavy metal supergroup backed by actual rock star progeny and a literal founding father of the genre, we finally have our answer. It's called Jack Sabbath, and it is every bit as glorious, chaotic, and loud as you're imagining.
At the Power to the People Festival at the Merriweather Post Pavilion in Columbia, Maryland, festival-goers got front-row seats to what can only be described as the world's highest-octane heavy metal daycare. Jack Black took the stage alongside a crew of ridiculously talented young musicians, including guitar prodigy Roman Morello (son of Rage Against the Machine’s Tom Morello) and rhythm master Revel Ian (son of Anthrax’s Scott Ian), along with powerhouse drummer Yoyoka Soma and bassist Hugo Weiss.
Heavy Metal Royalty Steps Onstage
As if having the next generation of rock royalty shredding onstage wasn't enough, the group brought out a genuine legend: original Black Sabbath bassist Geezer Butler himself. Together, they ripped into an epic performance of Black Sabbath's legendary anti-war anthem, 'War Pigs.'
Seeing Geezer Butler lay down those iconic, earth-shaking bass lines alongside a band of teenagers—led by Jack Black doing what Jack Black does best—was pure magic. Roman Morello paid homage to guitar royalty by sporting a polka-dotted black Flying V guitar modeled after Randy Rhoads' iconic 1981 instrument, tearing through riffs with precision that blew the crowd away.
The Jack Sabbath set didn't stop there, either. The high-energy lineup sprinted through classic cuts including Black Sabbath’s 'The Wizard' and Ozzy Osbourne's timeless solo banger 'Mr. Crowley.'
Scarf Dynamics and Hip-Hop Crossovers
Because one legendary crossover is never enough when Jack Black is involved, he later hopped on stage with hip-hop pioneer DMC for a blistering performance of 'Walk This Way.' Showing classic rock solidarity, Jack Black wrapped several scarves around his microphone stand as a nod to Aerosmith frontman Steven Tyler. It was equal parts heartfelt tribute and classic theatrical energy.
The Otterly Interesting Part
There is something genuinely heart-warming about watching heavy metal—a genre often unfairly associated with gloom and doom—become a joyful family handoff across generations. When teenagers whose parents defined '90s alt-metal and '80s thrash stand shoulder-to-shoulder with a 1970s founding icon, it proves that real rock and roll isn't aging out; it's just getting passed down at the dinner table.
The Kids Are Definitely Alright
In an era where live music moments can sometimes feel overly polished, Jack Sabbath brought back pure, unadulterated excitement. It was a reminder that at its core, music is meant to be shared, celebrated, and played as loudly as possible.
