The Piano Concerto in B-flat Minor (1938, 39 minutes) by British composer Arthur Bliss (1891-1975) is sweeping, with a curious mixture of post-Romanticism and English pastoralism. The style sounds like a combination of Rachmaninoff and Ralph Vaughn Williams (when in his loud and virile moments), with the latter contributing the modal harmonies and clashing dissonances based on half steps and tritones.
I’m supposed that the work isn’t booked more often. It would be a real crowd pleaser.
The Naxos CD, with Peter Donohoe at the piano and the Royal Scottish National Orchestra (2002, 22 minutes), offers the Sonata for Piano, which seems to be in A Minor, but is very chromatic and toccata-like. It has three movements (Moderato marcato Adagio sereno< Allegro) and picks up momentum after a serene slow movement.
