With his former bandmate Mike Portnoy, he has produced all Dream Theater albums from 1999's Metropolis Pt. 2: Scenes from a Memory to 2009's Black Clouds & Silver Linings, and has been the sole producer of the band's albums released since Portnoy's departure in 2010. Petrucci was named as the third player on the G3 tour six times, more than any other invited guitarist. Joel McIver's 2009 book The 100 Greatest Metal Guitarists ranks Petrucci second, after Dave Mustaine. He was also named as one of the "Top 10 Greatest Guitar Shredders of All Time" by GuitarOne magazine. In 2012, Petrucci was ranked the 17th greatest guitarist of all time by a Guitar World magazine reader's poll.
John Petrucci was born on July 12, 1967, in Kings Park, New York, to an Italian American family. He picked up the guitar at the age of eight because his older sister was allowed to go to bed later in order to practice the piano. However, he decided to quit the guitar when his attempts to stay up late were unsuccessful. He picked up the guitar again at the age of 12. Petrucci has said he committed to practicing guitar 6 hours a day when he discovered it was his passion. His early influences were bands like Led Zeppelin, Black Sabbath, AC/DC, and later developed an interest in progressive rock and heavy metal, exemplified by Rush, Yes, Iron Maiden, Dixie Dregs and Metallica.
