Henry Purcell (1659-1695) held numerous appointments at the Royal Court and Westminster Abbey and is considered by many to be the greatest ever English-born composer. His prolific work covered all fields: orchestral ecclesiastical operatic theatrical incidental and chamber music were all enriched by his output. The evocative anthem Thou Knowest Lord (Z 58) was written in 1687 and later included in William Croft'ssetting of the Burial Service 'for reasons obvious to every artist'. It has been sung at every British State Funeral since.This arrangement by Vincent Knight is for SAB Choir and Organ.
