Between the 1960s and the 1990s, Manuel Alejandro, born into a family of musicians, composed an endless string of love ballads for many artists, including Hernaldo Zúñiga, Enrique Guzman, and Plácido Domingo. Among his songs are ‘Lo mejor de tu vida’ and ‘Un hombre solo’ which are amongst the most famous in Julio Iglesias’ repertoire. He composed entire albums for Mexican singer Emmanuel. Between 1972 and 1974, Alejandro released three albums as a singer. He is, however, best known for his work as a composer, arranger, and producer for Raphael Martos.
