I'm really glad that there are fans of Dyson on here. I think that he is still criminally underrated - every one of his choral and orchestral scores has so much to offer. Particular favourites of mine are
Quo Vadis,
St Paul's Voyage to Melita,
Nebuchadnezzar,
The Blacksmiths (either in the full orchestral version, but especially in the version for two pianos, strings and timpani) and the two late concertos for string orchestra. He's a composer with a very individual harmonic style and a wonderful sense of choral effect.
Coming soon from the pen of Paul Spicer is the first full-length study of the composer -
