[Wikipedia on Maurizio De Angelis]: 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: during their career, they were variously known as G&M Orchestra, Barqueros, Charango, Kathy and Gulliver, Hombres del Mar and Dilly Dilly.
