Duncan Dhu were a Spanish pop-rock group of the 1980s. The group was founded in San Sebastian, Spain in 1984 by singer Mikel Erentxun (Aristogatos), and Diego Vasallo, and Juan Ramón Viles (Los Dalton).

The name Duncan Dhu comes from the book "Kidnapped: The adventures of David Balfour" by Robert Louis Stevenson where there is a character named Duncan Dhu, who is a lover of music. Their style was based on an acoustic and simple pop-rock with a touch of rockabilly in great contrast with the more radical rock played in the area at the time.

After being hired by 'Grabaciones Accidentales, S.A.' they contributed with two songs (Mi Amor and Bésame Mucho) to the new bands compilation La única alternativa (The Only Alternative).In 1985 they recorded their first album, Por Tierras Escocesas (Around Scottish Lands), and Canciones (Songs) a year later, both produced by Paco Trinidad.

The songs were immediately successful and gave them big popularity. After even more successful El Grito del Tiempo (The Cry of Time, 1984) and Grabaciones Olvidadas (Forgotten Recordings, a compilation of B-Sides, 1989) they became a duo and recorded the double album Autobiografía (Autobiography), with collaborations by Black and Sam Brown among others.

They later also had several hits such as "Esos Ojos Negros" ("Those Black Eyes"). They finally came to a close as a band with their final cd, "Crepúsculo y Crudités" (Sunset and Crudités ) which was more orchestrated and softer than their older music.

Their most known hit is "En Algún Lugar" ("In Some Place"). The song was initially featured in Canciones, but it was the remix included in El Grito del Tiempo that became widely popular.
