Dave Grohl has made it a habit to invite talented young guitarists onstage to perform during Foo Fighters concerts, and he did it again at Friday’s show at the Blossom Music Center in Cuyahoga Falls, Ohio.

In video shared on YouTube, Grohl welcomes 17-year-old Lucas Gregetz of Essex, Ont., to do a little shredding during the band’s performance of “Monkey Wrench”.

“Once I had the guitar, I just let loose and I really didn’t care … Honestly, it felt like a dream. It was surreal. It didn’t feel like I was actually there,” Gregetz told the National Post of what it was like to perform in front of a crowd of 17,000.

“In the middle of the song, [Grohl] kept pointing and saying, ‘Look at all the people!’” he added said. “I just went, ‘Oh my God, I know!’”

As the Post points out, a lot of practice and a lot of luck went into the teen landing a coveted invite onstage after his father surprised him with front-row tickets, which led him to bring along a homemade sign reading, “Please let me jam Monkey Wrench.”

“I’ve actually been planning this for a few years,” Lucas said, revealing that he brought a similar sign to the band’s Toronto show, but went unnoticed. “Then KISS guy went up and nailed it, and I thought, ‘Aw, I can’t do it now.’ But then I thought, ‘Well, I’m still gonna do it. I just wanna play. I just wanna jam.”
