On his website, the following can be found:
James’ musical tastes are quite varied as he names Metallica, Aerosmith, Van Halen, Journey and Judas Priest as well as classical composers Mozart, Vivaldi and Beethoven as favorites. Influential vocalists include Steve Perry (formerly of Journey), Freddie Mercury, Sting, Paul Rodgers and Nat King Cole.
In discussion with Artisan News, James said the following:
I would say Sleeping With Sirens, I See Stars, Bring Me the Horizon. Those guys off the top of my head. I’ve always liked Ryan Tedder from One Republic, I think he’s got a great voice. It’s got a lot of emotion.
Killswitch Engage … I’m saying the names of the bands cause I’m drawing a blank on these guys’ names right now … Tesseract … he’s got a great voice. My son turned me on to a lot of those bands. I’ll walk past his bedroom and be like ‘who’s that?’ Tesseract is a great band … really excited with those guys.
