The music world is in mourning today after the loss of a towering figure whose riffs defined a generation and whose songs are etched into the DNA of classic rock.

He was known not only for his unforgettable sound, but for the electric presence he brought to every stage he stepped on. Across decades and continents, he collaborated with the biggest names in the industry — his work was everywhere, even if you didn’t know it was him behind the curtain.

Loved ones say he passed peacefully, surrounded by those dearest to him. His health had been a private struggle in recent months, including recent surgery. But his spirit, they say, remained “as fierce and fiery as his guitar solos.”

Only then was it revealed that Rick Derringer, the legendary guitarist behind hits like Hang On Sloopy and Rock and Roll Hoochie Koo, had passed away at the age of 77.

Derringer — born Rick Zehringer — skyrocketed to fame at just 17 when he helped found The McCoys and delivered one of the most iconic rock anthems of the ‘60s. He went on to collaborate with stars like Alice Cooper, Cyndi Lauper, and even produced Weird Al Yankovic’s debut album.

He was also the force behind Real American, the theme song beloved by wrestling fans as the entrance anthem of Hulk Hogan. His music found new life when Rock and Roll Hoochie Koo was featured in Netflix’s Stranger Things.

As tributes pour in from fellow legends like Vinny Appice and John Corabi, one truth remains clear — Rick Derringer wasn’t just a musician. He was a movement. And his sound will echo far beyond his final note.
