Alter Bridge is an American heavy metal band from Orlando, Florida, formed in 2004. The band consists of lead vocalist and guitarist Myles Kennedy, lead guitarist and backing vocalist Mark Tremonti, bassist Brian Marshall, and drummer Scott Phillips. Since the band's formation, there have been no line-up changes.

Following Creed's disbandment in 2004, then-former members Tremonti, Marshall, and Phillips began working with Kennedy, formerly of The Mayfield Four. Named after a bridge that once existed on Alter Road near Tremonti's former home in Detroit, Michigan, Alter Bridge released its debut album, One Day Remains, the same year. Despite mixed reviews, One Day Remains went on to be certified gold by the RIAA. Driven by the release of the single "Rise Today", the band released its second album, Blackbird, to more positive reviews in 2007, with their band embarking on a successful world tour in support.
