The full discography of rock musician Myles Kennedy consists of eleven studio albums, two concert films, four live albums, two extended plays, and thirteen singles in total, in addition to eleven studio tracks that he has appeared on as a featured artist, one of which was a single.  Born in Boston on November 27, 1969, Kennedy is currently a member of the rock band Alter Bridge, with whom he has released four studio albums, two concert films, and several singles.  He is also the frontman of Slash's touring group, and with Slash he has released a live album, "Live in Manchester", the first of a series of live albums released throughout the summer of 2010, and "", another live album released in 2011.  In 2012, he released a collaboration studio album with Slash titled "Apocalyptic Love", which is billed to Slash featuring Myles Kennedy and the Conspirators, as well as the 2014 followup titled "World on Fire".  With The Mayfield Four, he released two studio albums, two extended plays, and four singles; with Citizen Swing, two studio albums; and with Cosmic Dust, one studio album. Myles Richard Kennedy (born Myles Richard Bass; November 27, 1969) is an American musician, singer, and songwriter, best known as the lead vocalist and rhythm guitarist of the rock band Alter Bridge, and as the lead vocalist in guitarist Slash's backing band, known as Myles Kennedy and the Conspirators.  A former guitar instructor from Spokane, Washington, he has worked as a session musician and songwriter, making both studio and live appearances with several artists, and has been involved with several projects throughout his career. Citizen Swing was an American alternative rock band from Spokane, Washington.  The band released two albums, "Cure Me With the Groove" and "Deep Down", before disbanding in 1996.  "Cure Me With the Groove" was a jazz-influenced pop album best described as Stevie Wonder meets Stevie Ray Vaughan, while "Deep Down" was a much heavier album, dropping all of the pop pretense in favor of heavy guitars, soaring vocals, solid and infectious beats and a bit of the 'jazz flair' of the trumpet.  Vocalist and lead guitarist Myles Kennedy, formerly of Cosmic Dust, eventually went on to front The Mayfield Four and later Alter Bridge. Cosmic Dust, also known as the Cosmic Dust Fusion Band, is an instrumental jazz band formed in 1990 by Jim Templeton.  The band was the first well-known group that guitarist Myles Kennedy played in.  The original lineup consisted of Jim Templeton on keyboard, Gary Edighoffer on saxophone, Clipper Anderson on double bass, Myles Kennedy on guitar, and Scott Reusser on drums.  Kennedy eventually left the band and went on to become the lead vocalist/lead guitarist for a jazz fusion group called Citizen Swing and later an alternative rock band called The Mayfield Four.  Kennedy is now fronting and playing guitar for the hard rock/alternative metal band Alter Bridge, which he helped form with Creed members Mark Tremonti, Scott Phillips, and Brian Marshall in 2004, and is also the lead vocalist for Slash's solo band on tour. "Back from Cali" is the second single and fourth track from Slash's self-titled solo album.  It is one of the two songs on the album to feature Alter Bridge frontman Myles Kennedy on lead vocals, the other being "Starlight."  The song was written and recorded in March 2010 added to the album's track listing at the last minute since Slash was so impressed with Kennedy's performance on "Starlight."  He later asked Kennedy to front his solo touring band.  Both "Back from Cali" and "Starlight" have since become regular features in Slash's live shows. Chapter VII: Hope & Sorrow is the seventh studio album from the Heavy metal band Sevendust, and the last to feature guitarist Sonny Mayo who was replaced by original guitarist Clint Lowery before the release of the album.  It was released on April 1, 2008, through the band's own 7 Bros.  Records, in conjunction with Warner Music Group's Independent Label Group.  The album features guest appearances by Chris Daughtry (Daughtry), Myles Kennedy (Alter Bridge, Slash), and Mark Tremonti (Alter Bridge, Tremonti, Creed).
