Jack Black's Mr Crowley with Roman Morello and Hugo Weiss

Jack Black doing Ozzy. That alone is worth the click. But this is more than a celebrity cover.

Roman Morello on guitar. Yes, Tom Morello’s son. The kid plays like he grew up in a house full of Marshalls. Which he did. His solo on “Mr Crowley” has the precision of someone twice his age. Clean bends, controlled vibrato, and enough fire to make Randy Rhoads nod from wherever he is.

Yoyoka Soma on drums. Teenage drummer from Japan who hits the kit like Bonham and Paice had a kid and that kid decided sleep was optional. Tighter than a snare drum at Wacken. She doesn’t just keep time. She drives the entire performance forward.

Hugo Weiss on keys is the one who makes this work. “Mr Crowley” is a keyboard song. The intro that everyone remembers — the slow, ominous build before Rhoads’ first note — that is keys. Get that wrong and the whole song collapses. Hugo Weiss does not get it wrong. The atmosphere lands, the build holds, and when the band finally kicks in, the room is already inside the song. Watch the video and listen to what the keys are doing under the solo. That layer is the difference between a cover and a performance.

Revel Ian on bass keeps the low end locked. The whole band plays like they’ve been touring together for years. They haven’t. This was part of “Back to the Beginning,” a charity event supporting Cure Parkinson’s, Birmingham Children’s Hospital, and Acorn Children’s Hospice.

Metal raising money for sick kids. No irony. No angle. Just musicians playing loud and doing good. Jack Black screaming “Mr Crowley” into a microphone while a room full of people lose their minds. That’s the video. That’s enough.
