La Casa Azul (English: The Blue House) is a Spanish indie pop band that combines many of the qualities of 1960s American pop bands like the Beach Boys and 1970s European disco-pop acts like ABBA with clean, clear production reminiscent of Shibuya-kei.

Milkyway is in fact the sole performer on the records and uses the band "members" (who do not give interviews and whose last names have never been disclosed) in order to project an image.

In 2007, when the video of their newest single "La revolución sexual" was released, it was announced that the five members (sometimes called androids) were going to be relegated to some dancing sequences while Milkyway took lead of the band.

La Casa Azul got a spot into the final of the Spanish selection process for the Eurovision Song Contest 2008, which would take place in Belgrade on May 24.

MySpace altogether with the Spanish Broadcasting Television TVE run a preselection event called Salvemos Eurovisión.
