Erik Chisholm (anything)
Ronald Stevenson: Passacaglia on DSCH (Dimitri Shostakovich)
A huge amount of Chisholm can be ordered via the Scottish Music Centre, but in my experience you will need a credit card with a £6,000,000 credit limit. I think that they make up the scores to order which i guess explains the expense. The buggers charged me £50 just for the 2nd concerto.
Stevenson has his own society where you can order scores, but i have no experience with them as his music does not really interest me, albeit i recently came across a copy of his concerto which i understand some people highly rate.
