John Petrucci is an American guitarist best known as a founding member of the progressive metal band Dream Theater. He has produced (along with his bandmate Mike Portnoy) all Dream Theater albums since their 1999 release, Metropolis Pt. 2: Scenes from a Memory. Petrucci was named as the third player on the G3 tour six times, more than any other invited guitarist. GuitarOne ranked him as the 9th Greatest Shredder of All Time.
Petrucci first played guitar at the age of eight when he noticed his sister (who was taking organ lessons at the time) was allowed to stay up past her bed time to practice. He soon dropped it when his plan failed. At age 12, he began playing again when he was invited into the band of his friend Kevin Moore, who would later become the first keyboardist of Dream Theater. Petrucci began to practice in earnest whilst exercising physically. He was a largely self-taught guitarist who developed his skills through attempts to match the skill of his idols, who included Steve Morse, Steve Howe, Steve Vai, Stevie Ray Vaughan, Al Di Meola, Alex Lifeson and Allan Holdsworth. He has jokingly referred to his guitar idols as "the Steves and the Als".
Petrucci attended Berklee College of Music in Boston with childhood friend John Myung (bass), where they met future bandmate Mike Portnoy (drums). These three in addition to another childhood friend of Petrucci and Myung, Kevin Moore (Keyboards), formed the band Majesty, which would later become Dream Theater.
While Dream Theater is what Petrucci is most commonly associated with, he is also a part of the project band Liquid Tension Experiment and has appeared as a guest on several records by other artists such as the Age of Impact album by the Explorer's Club.
In 2001 he was invited by Joe Satriani and Steve Vai to tour with them on the popular G3 guitar tour, which exposed him to a massive number of new fans and inspired him to record a solo album. Suspended Animation was released on March 1, 2005, and made available for order from his web site. He also appeared on the 2005, 2006 and 2007 G3 tours.
Petrucci also wrote and recorded two instrumental soundtrack songs for a Sega Saturn game titled Digital Pinball: Necronomicon. Each track is roughly two minutes long and they are simply titled "Prologue" and "Epilogue". Petrucci is an avid Sega Saturn gamer, and has revealed in interviews that he never tours without one.
John Petrucci won the "Guitarist of the Year 2007" award recently in Total Guitar Magazine.
