FRANK ZUMMO Spills All in Rock Sound’s “7 of 30” — Sum 41, Electric Callboy & New Memoir

In the latest installment of Rock Sound’s “7 of 30” series, legendary drummer Frank Zummo (of Sum 41 fame) digs deep — talking past, present, and what’s next. This episode finds him reflecting on his return to stage with Electric Callboy over the summer, reuniting with Sum 41’s frontman Deryck Whibley, and launching his memoir Unbreakable Rhythm, which is out now.

Zummo recounts the origins of his career — including a pivotal moment when Kevin Lyman (founder of the original Warped Tour) pushed him into his first record deal — and a wild Hollywood party where he reportedly met Prince, an anecdote that captures the improbable ups and downs of a life lived in music. Whether he’s drumming stadium shows or navigating rock-star reality, Zummo’s energy remains undimmed.

The conversation also touches on Zummo’s recent collaboration with Electric Callboy: their summer shows offered a mix of Sum 41 nostalgia and fresh-metal mayhem. According to him, performing with Electric Callboy reignited that touring fire — a chance to reconnect with the thrill of live performance and experiment with new sonic energy.

Finally, Zummo lifts the curtain on his inspirations and his new book Unbreakable Rhythm — a memoir chronicling decades of heavy music, survival, and personal growth. Paired with a curated seven-song mini setlist that spans punk, metal, and groove, this Rock Sound entry isn’t just an interview — it’s a masterclass in the life and legacy of a drummer who refuses to sit still.
