Sun-Dogs is a setting of a poem by Michael Symmons Roberts. The text is richly allegorical, iconographic with a deep well of symbolism. The metaphors are complex, evoking a range of emotions and images, dark and terrifying one minute, radiant and ecstatic the next.

This is a through-composed work comprising four sections and lasting about twenty five minutes. The final section is a coda involving a choir and the text is a poem with the same title by Michael Symmons Roberts.

The piece is essentially abstract, but was inspired by a myth from the Mabinogian (a collection of ancient Welsh stories). The Birds of Rhiannon are mystical, angelic presences which appear and sing on the death of Bran – a Fisher King-type figure who sacrifices his life (he is beheaded) for the sake of peace between two warring peoples. In essence the work could be described as being a dramatic concerto for orchestra with a mystical coda for choir.

Co-commissioned by the BBC Proms and the Philadelphia Orchestra and Chorus, with the Hilliard Ensemble and the Westminster Cathedral Choir, Quickening sets poetry by Michael Symmons Roberts exploring themes of birth, new life and new impulses.

The work’s three-fold vocal layers juxtapose mysticism and hyper-realism, painting a canvas at one turn intimate and private, at the next epic and celebratory.

The Sacrifice is an opera in three acts composed by James MacMillan with a libretto by the poet Michael Symmons Roberts based on the Branwen story of the Welsh myth collection, the Mabinogion.

The production was staged by Welsh National Opera, directed by Katie Mitchell and conducted by the composer.
