A Mass of Life is the largest of Delius's concert works, written for four SATB soloists, double choir and orchestra. It was dedicated to Fritz Cassirer, who had had an important hand in choosing the passages from Nietzsche's text.
The work was completed in 1905. Part 2 was first performed in Munich in 1908, with a complete performance in London a year later. The conductor for this performance was Thomas Beecham.
