I know many out there will have neither time nor inclination to listen to all ( or any) of this: my "go to" music when I need some head peace.
George Butterworth, had he survived, would have been one of the most significant British composers of the 20th century.
The premier of this piece of music was a few months before the outbreak of the first war. Butterworth enlisted and served as a junior officer until he was killed in August 1916 during the battle of Somme.
