The first release by the six-piece band was "Chocolate Kings" in 1975. Featuring a harder rock sound, it had modest success at home but was their least popular album in Italy so far. The same album was released with different cover art by Manticore in the UK and by Asylum Records in the US. The controversial US/UK cover showed a chocolate bar in a partially peeled Stars and Stripes wrapper on the front, along with the crumpled and discarded wrapper on the back. PFM appeared on the BBC television show "The Old Grey Whistle Test" in 1976 performing the title track to the album. The album reached the UK top 20 but was less successful internationally. Mauro Pagani left the group following "Chocolate Kings" to pursue a solo career.
