Nelson and Trimble were both vital catalysts in the musical life of Northern Ireland. Havelock Nelson was employed by the BBC in the Province; he was a pianist, composer, conductor and operatic animateur. Joan Trimble was best known as a pianist - notably in the duo with her sister Valerie - but also she was a distinguished composer. The present book arose from an AHRC-funded project (2008-2010) researching into the musical life of Northern Ireland, and is the first publication to examine the many facets of these two major figures.
