Former Dream Theater drummer Mike Portnoy discussed the band’s musical influences in a recent interview with Ultimate Guitar. The veteran musician highlighted Rush’s significant impact on Dream Theater’s compositional style throughout their four-decade career.
“There’s always Rush in every Dream Theater song has ever written throughout our entire career, dating back 40 years ago, to the very first ‘Majesty’ demos,” Portnoy said. “I mean, Rush was always our biggest collective influence. So, yeah, there’s no question that that stuff comes through.”
“I mean, there’s some riffs in ‘The Shadow Man [Incident]’ that sound like they could have been off of ‘Hemispheres’, some ‘Permanent Waves’,” he continued. “Night Terror’ has got a whole big kind of 7/8 section, which is very ‘Natural Science’-ish. So yeah, that stuff inevitably comes through no matter what.”
Dream Theater is preparing for the release of their new studio album ‘Parasomnia’.
