Smash Mouth is an American rock band from San Jose, California. The band was formed in 1994, and was originally composed of Steve Harwell, Greg Camp, Paul De Lisle and Kevin Coleman as lead vocals, guitar, bass and drums respectively. They are known for such songs as "Walkin' on the Sun" (1997) and "All Star" (1999).
They have at times played third wave ska music, but have generally adopted retro styles covering several decades of popular music. They have also performed numerous covers of popular songs, including The Monkees' "I'm a Believer", War's "Why Can't We Be Friends" and The Beatles' "Getting Better." The band's 1999 album Astro Lounge is their most successful album, both commercially and critically, to date.
