I stumbled upon Psalmes, Songs and Sonnets listening to Radio 4 as I was driving back from Chelmsford yesterday.
William Byrd is regarded as one of England's greatest composers. He lived through turbulent times through the Sixteenth and early-Seventeenth Centuries, witnessing both significant religious and political change. Despite this, he composed some of the finest music of his time for both the Catholic and Anglican Church.
Never heard of him as far as I can remember. Beautiful music.
