Featuring Wally Tax (vocals), Ronnie Splinter (guitar), Appie Rammers (bass guitar), Tom Krabbendam (guitar), Leendert "Buzz" Busch (drums), and Frank Beek (bass guitar 1968-1969), the band exemplified the "Nederbeat Sound", a raw, Dutch take on rock 'n' roll created in the wake of the 1960s British Invasion.
The Outsiders released three full-length records, Outsiders and the singles collection Songbook in 1967, and C.Q. in 1968.
