Frank Martin was arguably Switzerland's greatest composer. His shimmering Mass for Double Choir, completed in 1926 as 'an affair between God and himself', is one of the finest settings of the 20th century, yet it had to wait forty-one years to be shared with others in its first performance. This collection of his choral music also includes his cantata for Switzerland's National Day and the Ode to Music, along with some charming part-songs. Eclectic and technically superb these pieces display a style that is serenely individual.
