The Scottish pianist Ronald Stevenson, now 86, is the Grand Old Man of Scottish music. A composer-performer in the grand tradition of Beethoven, Chopin and Rachmaninov, he has written a huge quantity of music for his own instrument, the piano, ranging from tiny miniatures to his best-known work, the monumental Passacaglia on DSCH. This first of a series of recordings by the young Scottish pianist Christopher Guild, strong advocate of contemporary and lesser- known repertoire, begins with an album inspired by the music of Scotland itself and its Celtic neighbor, Ireland.
