are surpassed by other choirs, but they are undoubtedly authentic in the sense that they sing Gregorian chant as part of their daily worship. As a reviewer in Gramophone puts it: "The ensemble is not always perfect, but if these are not professional singers, they are, and they sound like, truly professional monks." Mozarabic chant Along with Ensemble Organum, the monks of Silos are one of the few choirs to have recorded Mozarabic chant, for example on a 1970 album for German early music/baroque label Archiv Produktion. Access for the public The cloisters and pharmacy are open to the public. Visitors are also able to attend services such as vespers in the abbey church. Access to the library is restricted to researchers.
