The original incarnation of El Sueño de Morfeo was Xemá, a Spanish rock group that formed in 2000 and included both singer Raquel Rosario and guitarist David Feito (Feito, in fact, was the leader). After releasing an album with Xemá, in 2003 Feito and Rosario decided to begin a new project, and invited guitarist Juan Luis Suárez to join their band, which they called El Sueño de Morfeo.
