Maroon 5 is an American pop rock band that originated in Los Angeles, California. The group was formed in 1994 as Kara’s Flowers while its members were still in high school and originally consisted of Adam Levine (lead vocals, guitar), Jesse Carmichael (guitar, backing vocals) Mickey Madden (bass guitar) and Ryan Dusick (drums). Kara’s Flowers signed to Reprise Records and released an album, The Fourth World, in 1997. After a tepid response to the album, the band parted ways with the record label and the members attended college. Dusick and Madden stayed local at UCLA, while Levine and Carmichael relocated to the east coast to attend Five Towns College. While Levine and Carmichael were in New York, they began to take notice of the urban music surrounding them and later let the style influence the songs they wrote.
In 2001, the band regrouped, with guitarist James Valentine added to the line-up, and pursued a new direction under the name: Maroon 5. At this point, Jesse Carmichael switched to playing the keyboards and this has become his main instrument in the band. After these changes, Maroon 5 signed with Octone Records and released their debut album, Songs About Jane, in June 2002. The album’s lead single “Harder to Breathe”, received heavy airplay, which helped the album to debut at number six on the Billboard 200 chart. The band won the Grammy Award for Best New Artist in 2005. For the next few years, the band toured extensively worldwide in support of Songs About Jane and produced two live recordings: 2004’s 1.22.03.Acoustic and 2005’s Live – Friday the 13th. In 2006, Ryan Dusick officially left the band after suffering from serious wrist and shoulder injuries and was replaced by Matt Flynn. The band recorded their second album, It Won’t Be Soon Before Long… (read the complete article at Wikipedia)
