The dances presented on this recording are described in around a dozen manuscripts which are nearly all of Italian origin. The principal sources all start with a theoretical section on the concept of dance, placing it in a philosophical context, followed by choreographic descriptions, partly accompanied by music. Almost all the dances are attributed to two 15th-century masters, Domenico da Piacenza and Guglielmo Ebreo da Pesaro. Formed in 1993, Les haulz et les bas has established itself as one of Europe’s most active mediaeval wind ensembles. The work of the ensemble has achieved international recognition: it has performed and given lectures at many leading Early Music Festivals including Bruges, Antwerp, Utrecht, Cambridge and Berlin, at the Universities of Oxford and London, the Historic Brass Society and the Galpin Society, Edinburgh and the Schola Cantorum Basiliensis.
