“It is probably the first time an Arab singer interprets both the ancient Spanish and the Arabic part of the muwaxahas” comments Luis Delgado referring to his new album AS-SIRR. The Arab mentioned is the well-known Mohamed Serghini el Arabi from Morocco who once again takes the vocal part on a Delgado album. The current one is dedicated to the muwaxahas, a poetic form originated in medieval Al-Andalus, whose roots can be traced back until the 9th century. Delgado offers us a new musical interpretation of these poems who reflect the different cultural influences of the Al-Andalus community at that time.
