 In the same year and in the same columns his oratorio "A Song on the End of the World", named after a Czesław Miłosz poem from Nazi-occupied Warsaw and written as the last pre-millennial Elgar Commission of the Three Choirs Festival at Worcester, was hailed as "thrilling, apocalyptic and profoundly affecting".His 89-minute oratorio for tenor solo, double chorus and organ, "The Cloud of Unknowing", received international acclaim following its premiere in May 2006 at London Festival of Contemporary Church Music (James Gilchrist, tenor, Jeremy Filsell, organ, and the Vasari Singers under their conductor, Jeremy Backhouse) and the CD release by the same artists in September 2007 (Signum Records).In January 2012 Naxos released Pott's sacred choral works, performed by the Oxford-based chamber choir Commotio under the direction of Matthew Berry.
