Cor Cyfoes is a Cardiff based chamber choir formed in 2009 by Richard Jackson and Matthew Clark for the recording, workshopping and performing of new choral music. The choir is made up of emerging singers and composers from both the Royal Welsh College of Music and Drama, and Cardiff University.

Current repertoire includes works by Liz Lane, Jack White, and Sarah Passe.

The choir has recently been invited to perform Belshazzar's Feast with UWE Symphony Orchestra and was also involved in the world premiere of Thomas Morgan's 'The Passion of Christ'.
