In addition to frequent performances at international festivals, the group has pursued an active recording schedule. Their remarkable discography has averaged one release for each year since their inception. Notable areas include early English music (John Dunstable and the recently discovered Worcester fragments), the Franco-Flemish school of composers (including Johannes Ockeghem and Josquin Desprez but also the obscure Loyset Compère), and Notre Dame polyphony (Léonin and Pérotin). Their recording John Dunstaple won the Early Music award from Gramophone magazine in 1996; Loyset Compère, Popes and Antipopes, and Worcester Fragments have also received nominations.
The founding members -- countertenor Robert Harre-Jones, tenors Angus Smith and Charles Daniels, and baritone Donald Greig -- also pursued crossover projects, most notably their work with the jazz group Perfect Houseplants (Extempore) and their medieval/modern War Requiem with actor Robert Hardy. In the early 2000s, Daniels was succeeded by Mark Dobell, and later, Harre-Jones by Matthew Venner.
