Veljo Tormis (born 7 August 1930 in Kuusalu) is an Estonian composer, regarded as one of the greatest living choral composers and one of the most important composers of the 20th century in Estonia. Internationally, his fame arises chiefly from his extensive body of choral music, which exceeds 500 individual choral songs, most of it a cappella. The great majority of these pieces are based on traditional ancient Estonian folksongs (regilaulud), either textually, melodically, or merely stylistically.
His composition most often performed outside Estonia, Curse Upon Iron (Raua needmine) (1972), invokes ancient Shamanistic traditions to construct an allegory about the evils of war. Some of his works were banned by the Soviet government, but because folk music was fundamental to his style most of his compositions were accepted by the censors.
More recently, Tormis' works have been lionized in worldwide performances and several recordings by Tõnu Kaljuste and the Estonian Philharmonic Chamber Choir. In the 1990s, Tormis also began to receive commissions from some of the pre-eminent a cappella groups in the West such as the King's Singers and the Hilliard Ensemble.
