Inspired by his life-long interest in chant and choral music Paul Mealor?s De profundis pushes the boundaries of the human voice in a style synonymous with Russian orthodox music.In spring 2012 this piece sparked the 'Bass Hunter' competition - a world-wide talent search for the lowest human voice in existence. The note an ?E? (329 Hertz) is six notes below the lowest note ever written for a choral piece (from Rachmanivov?s ?Vespers? a B flat) and a whole tone lower than the Guinness World Record-holder - a sung ?F sharp?. The piece has since been recorded featuring the winner of the competition Tim Storms (Decca 3709935).
