Ruth Gipps's Violin Concertos
The Ruth Gipps Violin Concerto was written in 1943, so it lies outside the post-1945 period I specified. She did write a Concerto for Violin, Viola and small orchestra in 1957 but that is her only post-war unrecorded concerto. My list was of those composers who wrote five or more that have not made it to cd. There are a number of others-Arnold Cooke, Stanley Bate, Graham Whettam, William Mathias, William Wordsworth, Peter Racine Fricker who wrote three or four such unrecorded concertos.
