El Sueño de Morfeo, often shortened to ESDM is a Spanish three-piece band made up of Raquel del Rosario, David Feito, and Juan Luis Suárez. They represented Spain in the 2013 contest with the song Contigo Hasta el Final. It finished 25th place with just 8 points.

The band was originally formed in 2002 under the name Xemá, with a clear influence of Asturian folk music. Their debut album, Del interior, was released that same year, but failed to generate commercial success. This album was recorded while David Feito, from Asturias himself, and Raquel del Rosario, from the Canary Islands, were music teachers at the Colegio Internacional Meres in Siero, Asturias, together with fellow teachers Andrés Alonso (keyboard and accordion) and Antón Fernández (bass guitar and guitar). After the launch of this first album, the band had to decide if they would go on as Xemá or create a new project, opting for the latter.
