Ocean Music Ltd. was founded in 1978 by composer John Du Prez as a production company for his own music. In the same year he began a long association with Monty Python which enabled the company to go from strength to strength producing many scores for film and TV. In 1988,  following the success of A Fish Called Wanda, Du Prez  founded Ocean Music LA Inc., a wholly owned American subsidiary based in Santa Monica. This enabled him to become established as a successful international film composer, particularly after the release of Teenage Mutant Turtles I, II & III and its Platinum soundtrack album.


In 2002 he composed  with Eric Idle the music for the Broadway hit musical Monty Python's Spamalot which won Tony Award for Best  Musical 2005. The Original Cast Album won them both Grammy Awards as Producers. In 2008 their comic oratorio "Not The Messiah" was filmed in the Albert Hall for the 40th Anniversary of Monty Python and Ocean Music co-owns the rights to both the film (Sony Home Entertainment ) and the soundtrack album. Over the years Ocean Music has built up a large catalogue of published music including the original score for Spamalot of which it is the co-owner and co-publisher. In 2010 Du Prez established Ocean Music as a record label affiliated to Madison Gate Records, a division of  Sony Pictures, and more releases are planned for 2011.
