Banco de Gaia is an electronic music project from England, formed in 1989 by Toby Marks (born 1964, South London). The music of Banco de Gaia is mostly categorized as ambient dub and downtempo. Marks works to cross genres, often using Arabic and Middle Eastern samples against a bass heavy reggae, rock, or trance rhythm to produce deeply textured tracks that progress layer upon layer. In 1978, Marks began his musical career as a drummer in a heavy metal band. Marks moved to Portugal in 1986 and played Beatles music for tourists. See for more.
