The Beau Brummels were an American rock band. Formed in San Francisco in 1964, the band's original lineup included Sal Valentino (lead vocals), Ron Elliott (lead guitar), Ron Meagher (bass guitar), Declan Mulligan (rhythm guitar, bass, harmonica), and John Petersen (drums). They were discovered by local disc jockeys who were looking to sign acts to their new label, Autumn Records, where Sylvester Stewart--later known as Sly Stone--produced the group's early recording sessions. Initially, the band's musical style blended beat music and folk music and typically drew comparisons to the Beatles, while their later work incorporated other music genres such as psychedelic rock and country rock.
The Beau Brummels broke into the mainstream with their debut single, "Laugh, Laugh," for which they would later be credited for setting one of the aesthetic foundations for the San Francisco Sound, along with other bands such as the Charlatans; the song is in the Rock and Roll Hall of Fame list of the "500 Songs That Shaped Rock and Roll". The band's popularity continued with the subsequent album, 1965's Introducing the Beau Brummels, and the Top 10 single "Just a Little." The group's commercial success declined by the following year, at which time the financially struggling Autumn label was acquired by Warner Bros. Records. After recording an album of cover songs, ''Beau Brummels '66, the band released a pair of critically acclaimed albums: Triangle in 1967 and Bradley's Barn'' in 1968.
The band underwent several personnel changes, beginning with Mulligan's departure in 1965. Guitarist Don Irving joined the band in late 1965 when Elliott began to suffer seizures resulting from a diabetic condition, leaving him unable to tour with the band. Shortly after the release of ''Beau Brummels '66, Irving left the group when he was inducted into the armed forces. Petersen left to join Harpers Bizarre, reducing the Beau Brummels to a trio for the recording of Triangle. Meagher was drafted for military service in 1968, leaving Valentino and Elliott as the only remaining band members. The duo worked with prominent Nashville session musicians to record Bradley's Barn'' before parting ways in 1969 to focus on solo material and participate in projects by other artists. Four of the original Beau Brummels reformed in 1974 with one new member and the band released an eponymous album the following year.
