On 'As-Sirr' ("the secret") Arabo-Andalusian culture aficionado and multi-instrumentalist (guitar, lute, ud, saz, tar...) Luis Delgado tries to fathom the secret of medieval muwaxahas poetry. For the first time these ancient verses, which appear in Arabic, Hebrew and Romance (a predecessor current Spanish), are set to music. Don't let the seriousness behind this album deter you; 'As-Sirr' is a wonderful listening experience, a kind of soundtrack from a thousand and one nights and a reminder of the high-level Moorish-Arab culture that once dominated large parts of Spain.
