Owen Rees is a Reader in the Faculty of Music, Fellow, Tutor and Organist of The Queen’s College, and Senior Research Fellow of Somerville College. He is active as both scholar and performer and he also directs various vocal groups (Contrapunctus; The Choir of The Queen’s College and The Cambridge Taverner Choir). His research is concerned principally with music from 1450 to 1650, particularly in Spain and Portugal, and in England. His monograph on the largest surviving collection of early Portuguese musical sources — from the Monastery of Santa Cruz in Coimbra — deals both with Portuguese repertories and with cultural and musical connections between Portugal and other countries. He has edited music by three of the most important Portuguese composers of the period, Manuel Cardoso, Pedro de Cristo and Duarte Lobo. His published work on Spanish music has included studies of the works of Cristóbal de Morales and Francisco Guerrero, including issues of emulation. He has also written on the sacred music of William Byrd
