Creed was educated at King's College in Cambridge, Christ Church in Oxford, and the Guildhall School in London. He moved to Berlin in the mid-'70s, where he served as vocal coach and chorus master at the Deutsche Oper, and participated in several chamber music ensembles. He has since worked with a variety of choirs and orchestras, including the Berlin Philharmonic, Akademie für Alte Musik, Concerto Köln, Berlin Staatsoper, Berlin Staatskapelle, and most significantly, with the RIAS-Kammerchor, with whom he made numerous recordings. Recordings with that group received honors including the Cannes Festival Classical Award, the Edison Award, and a Diapason d'Or. In 2003, Creed was appointed artistic director of SWR Vokalensemble Stuttgart, a group with which he has continued to record a broadly diverse repertoire. In addition to his regular positions, he has participated in a variety of festivals, including Salzburg, Innsbruck, Lucerne, Edinburgh, the Venice Biennale, and Wein Modern.
