Opium Dream Estate (O.D.E.) is a musical project based in Paris, France, founded in november 2006 by singer/multi-instrumentalist Sébastyén D. (also involved Orchid's Children, The Funeral Warehouse, Lyan and managing the independent label Seventh Crow Records). Though Opium Dream Sound’s sound is rather difficult to describe as it is filled with many influences (ethereal, goth, neofolk, indie, neoclassical, etc.), it can be identifiable as (mainly) ethereal and neofolk. Sébastyén D. defines Opium Dream Estate's music as ethereal dreamwave.
