Guido And Maurizio De Angelis

The brothers were born in Rocca di Papa, near Rome.
Guido De Angelis in 1944 (22 December), and Maurizio De Angelis in 1947 (22 February). Their musical career started in 1963, where, after successfully publishing an LP, they became arrangers for. Their success led to many more albums in which they composed, arranged, and sang the music.
The De Angelis brothers were among the most prolific Italian musicians of the 1970s. In fact, they were forced to use different names for many of their projects to avoid over-saturating the market. One of these was Oliver Onions, which eventually became the name they were mostly identified.
Although they released many standalone albums, it is for their soundtrack work for which the De Angelis brothers are best known. Out of their many scores, which includes the main theme for the 1983 Italian cult movie Yor, the Hunter from the Future, undoubtedly the most famous and popular are those composed for the Terence Hill and Bud Spencer comedies. Their song "Dune Buggy" for the film Watch Out, We're Mad reached the top of the charts in Europe.
They are also known for their work on animated series, having composed original songs for Italian-dubbed anime (such as Doraemon, Ashita no Joe and Galaxy Express 999) and European series (such as Around the World with Willy Fog).
They made music also for title song of Sandokan serie, which was based on the novel E. Salgari.
They are also famous for writing and composing the themes to Dogtanian and the Three Muskehounds and Bobobobs.
