Jack Black is a man of many talents, from starring in classic movies like The Holiday and School of Rock to voicing Po in Kung Fu Panda and Bowser in 2023's The Super Mario Bros. Movie. And while slaying songs live in Tenacious D, his musical duo with Kyle Gass, Black's known to crush it on multiple instruments, including guitar, piano and...Sax-a-Boom.

Black showed off his Sax-a-Boom skills for the audience in a classic The Tonight Show Starring Jimmy Fallon clip from 2018, playing a bop that culminated in a magical collaboration with house band The Roots.

"I've seen you perform," Jimmy Fallon told Black. "Please go see Tenacious D in concert! It's unbelievable. You do a thing with a thing called a Sax-a-Boom."

Fallon then asked Black about his Kawasaki Sax-a-Boom, the brightly-colored rare toy instrument that he plays at his live shows.

"Well it's like a saxophone, but it's a Sax-a-Boom. A lot of people confuse them — because they look similar," said Black. "But a Sax-a-Boom is its own kind of instrument, that takes years to master."

"I was just wondering, if we happen to have one here — could you just maybe just show us?" Fallon asked, as he furnished a Sax-a-Boom out from behind his desk.

"You know how hard it was to find a Sax-a-Boom?" Fallon said of the toy, which has become a rare collectible since being discontinued. "Could you show us the magic? Could you give us a little taste?"

After a hilarious show of fake surprise, Black accepted the challenge.

The Kung Fu Panda 4 star blew into the Sax-a-Boom, creating a sax-y electronic sound as he pressed buttons, emitting different musical loops. Black then danced the party over to The Roots, who joined in.

"That is how you do it right there, everybody," said Fallon as he joined in on the funky fun.
