Music of extraordinary range and power composed at the dawn of the Space Age, Ronald Stevenson’s 'Passacaglia on DSCH' was long claimed as the biggest single stretch of music ever written for piano. It is a veritable world tour of styles as well as a single-minded exploration of its generating motif, and rising star James Willshire, Who received five-star acclaim in 2011 for his Delphian debut disc of music by Rory Boyle, has the technique and vaulting ambition to match both the work's grandeur and its immense wealth of detail.
