Moonmadness was originally released in March 1976. It was their fourth album and the last to feature the band's original line-up (Latimer, Bardens, Ferguson, Ward). After the success of the tightly structured, instrumental The Snow Goose in 1975, the band added vocals to their music again.
The tracks that comprised the album were conceived as a loose concept based on the individual personalities that made up Camel; Air Born about Andrew Latimer, Lunar Sea about Andy Ward, Chord Change about Peter Bardens and Another Night about Doug Ferguson.
