Their original lineup consisted of Hasu on guitar, Adi on drums, and Michi on double bass. Michi was replaced with Hasu's brother Simon and this lineup continued for five years until Toni replaced Adi as drummer. During this time the Peacocks released their first album. In 1997 they began touring Europe, Canada, the US and Japan and were signed up by Asian Man Records. More albums followed. Due to family commitments drummer Toni was replaced with Jurg in 2002.
Following their successful 2006 tour the band relocated to the US to record a new album at the Static Iguana, Indiana. In 2007 they resumed touring, with positive reviews from fans comparing their sound to Reverend Horton Heat and Rocket From The Crypt.
