Since his early years with Creed, Tremonti has received positive recognition as a guitarist and songwriter and has received a number of accolades, including one Grammy Award for Creed's single "With Arms Wide Open." He was also named "Guitarist of the Year" for three consecutive years by Guitar World, and in 2011 he was listed in Total Guitar magazine as the fourth greatest heavy metal guitarist of all time.
Tremonti was born on April 18, 1974, in Detroit, Michigan. He grew up in a Roman Catholic family of Italian descent in Grosse Pointe, just outside Detroit, for most of his childhood before moving to Wilmette, Illinois. He began to become enthralled with music, and bought his first guitar at the age of eleven. When he was fifteen, his family moved again to Orlando, Florida, where he enrolled in Lake Highland Preparatory School. During this time, his mother was diagnosed with systemic lupus erythematosus, which left Tremonti devastated.
After graduation, he moved to Clemson, South Carolina to attend Clemson University to major in finance. After his freshman year in college, he moved back to Florida to enroll in Florida State University, where he was reunited with his then future Creed band mate Scott Stapp, whom Tremonti had known in high school.
Tremonti is a founding member of the American hard rock band Creed. He formed the band with lead vocalist Scott Stapp in 1993 with fellow members Brian Marshall and Scott Phillips joining as bassist and drummer, respectively. Rhythm guitarist Brian Brasher was also briefly a member from 1993-95. Creed is recognized by many as one of the major acts of the post-grunge movement of the late 1990s and early 2000s. Tremonti and Stapp have been collectively recognized as one of the most prolific songwriting teams in all of rock music.
The band released their debut album My Own Prison in 1997 to strong mainstream success, selling over six million copies. Four singles were released from the album: "My Own Prison", "Torn", "What's This Life For", and "One". Each song reached No. 1 on Billboard's Hot Mainstream Rock Tracks chart, making Creed the first band to achieve such a feat with a debut album. My Own Prison was followed in 1999 by Human Clay, which was an immediate success and certified diamond and eleven times platinum by the RIAA. The band released four singles from Human Clay: "Higher", "With Arms Wide Open", "What If", and "Are You Ready". "Higher" spent a record-breaking 17 weeks on the top of the rock radio charts.
Creed also won their first, and to date only, Grammy Award for Best Rock Song for "With Arms Wide Open" in 2001. That same year, after a tour, the band released another multi-platinum selling album, Weathered, from which six singles were released: "My Sacrifice", "One Last Breath", "Hide", "Don't Stop Dancing", "Weathered", and "Bullets". It would be the band's only album without Marshall on bass; Tremonti handled the bass parts himself. The tour to support this record was overwhelmingly successful but ended with a considerably controversial concert in Chicago that ultimately led to the band's breakup.
