Alter Bridge is an American rock band that was formed in 2004 in Orlando, Florida. It consists of lead guitarist and backing vocalist Mark Tremonti, bassist Brian Marshall, and drummer Scott Phillips, all of whom are also members of Creed, alongside lead vocalist and rhythm guitarist Myles Kennedy, formerly of The Mayfield Four and the frontman of Slash's current solo project. Tremonti named the group after an actual bridge that once existed on Alter Road near his former home in Grosse Pointe Park, Michigan.

Despite Creed's multi-platinum success, Alter Bridge arose with only gold status with their first studio album, One Day Remains, which was released on Wind-up Records in August 2004 to generally mixed reviews. After the band's first tour, they dropped their contract with Wind-up Records in 2006 and signed with Universal Republic Records, releasing their second album, Blackbird, which was positively received by critics, in October 2007. The band spent the next two years touring and working on other projects before reconvening in 2010 to work on their third album. Titled AB III, the album was released in October 2010 on Roadrunner Records and was a critical success. In January 2011, the band's first live album and concert film, Live from Amsterdam, was finally released in stores after two years of delays. A second concert film, Live at Wembley, was released in March 2012. Since January 2013 the band has been recording their fourth studio album, expected to be released the same year.

Despite relatively low mainstream success and label support for the majority of the band's career, Alter Bridge's music has been critically successful, and the band has become known for its frequent, extensive touring and loyal fanbase. The individual members of Alter Bridge are also involved with various other projects, including solo and session work, Creed, and Kennedy's collaborations with Slash and former members ofLed Zeppelin. In 2009, Ultimate Guitar Archive named Alter Bridge the 36th greatest band of the decade.[1]
