The seven-piece band Cornucopia from Hamburg was formed in 1972 and consisted of Wolfgang Kause (voc), Christoph Hardwig (keyb, g), Kai Hendrik Motler (g), Wolfgang Bartl (b), Harry Koch (perc, effects), Rudy Holzhauer (perc) and Wolfgang Gaudes (dr). Their name is borrowed from Latin and is a mythological symbol of happiness that stands for fertility, generosity, wealth and abundance. The relatively large band attempted to express this wealth and abundance of musical ideas and forms of expression in September 1972 and February 1973 at the Windrose Studios in Hamburg. The producer was Jochen Petersen, who also helped out as a musician (sax, fl, g), quasi as the eighth member. Their first and only LP, Full Horn, was released in May 1973 on the cult label Brain and presented a cornucopia of colourful and varied ideas that did not follow a purely melody- or song-oriented philosophy. It was an eccentric, constantly changing fusion of progressive keyboard pads, hard guitar riffs, eccentric jazz rock, strange sound effects, idiosyncratic vocals, spacey electronics and psychedelic elements.

However, this cornucopia of avant-garde musical ideas failed to resonate at the time, and the band gave up in frustration just one year later. Their debut album thus remained their only release, which is now rare and highly sought after.
