An exclusive John Petrucci lesson, plus tabs of Lennon and Harrison's greatest post-Beatles pairing – only in the new Guitar World

"I've never even played an eight-string before, but I wanted to develop one and actually get into the studio and write a song on it" — John Petrucci

John Petrucci — who’s been anything but dormant during the pandemic daze — has capped off his recent burst of mad creativity with a blazing new Dream Theater album, A View from the Top of the World. In this issue, he fills us in on the challenges of producing his own band, his first-ever recordings with an eight-string guitar, why guitar playing is a bit like weight lifting — and exactly how he remembers his guitar parts on stage when an intricate, demanding song shatters the 25-minute mark.

PLUS: A PETRUCCI EXCLUSIVE!
The master himself breaks down the main guitar riffs in Invisible Monster, a brand-new Dream Theater track — complete with tabs and video (which you can check out below)!

The new issue of Guitar World is on sale now.
