AB III is the third studio album by American rock band Alter Bridge, released on October 8, 2010. Produced by Michael Baskette, the album is a departure from the band's first two albums; lyrically, it is a loose concept album dealing with darker lyrical themes of struggling with faith, while musically, the album's sound is more dynamic and progressive than previous recordings. AB III is also the first Alter Bridge album to be released on Roadrunner Records, making it the band's third consecutive album to be released on a different label. The album was released on Roadrunner Records worldwide except North America, where it was self-released on Alter Bridge Recordings via Capitol Records.The first single off the album, "Isolation", is the band's most successful single to date and was released on September 26, 2010, in the United Kingdom and November 9, 2010 in the United States. AB III received acclaim from music critics; for example, Artistdirect called it a "masterpiece". The album was certified Silver by the British Phonographic Industry, the same certification as Alter Bridge's 2007 album Blackbird.
