E. J. Moeran wrote these blistering words to his friend Lionel Hill on 16 January 1945. Dyson's general dismissal as a composer has been a common cry over the last fifty or sixty years. Very little of his music has held its place in the repertory. Of all his output only The Canterbury Pilgrims and the two sets of evening canticles in D and F for the Anglican liturgy of Choral Evensong are performed with any regularity. Thus it is important not only to record what was by any standards a remarkable life, but to rehabilitate Dyson's reputation and stir the embers of public interest in a wideranging list of works which are lyrical, passionate and engaging. At the core of his output lie major choral and orchestral compositions, a dramatic symphony, an outstandingly beautiful violin concerto, two balancing concertos for string orchestra, a ravishing, intimate piano concerto and much more besides.
