At eight years of age, Dmitry Pokrass began performing as a means of earning money. He declaimed poetry, beating off a chechotka. Touring cities, he absorbed the music of the suburbs of old Kiev, of military bands, Jewish weddings and celebrations, the cinema, synagogue services, and cheerful Ukrainian dances. During the years 1914–1917, Pokrass studied piano at the Petrograd Conservatory. As a student, he composed romances and songs for actors of a variety show. Has published a series of romances "Irmochka" with the description: "Intimate cabaret songs in the style of Isa Kremer, Vertinsky, Sabinin, Henkin". In the music of romances, he copied the stylistic manners of known actors, using the turns of fashionable tangos and other dances. He wrote songs of the "intimate genre" to be performed by Gipsy singer V. Shuysky: "The Bashful Tea Rose", "You Have Smiled at Me", "Warrant Officer Johns", and "Tango Dolores". In 1917 he returned to Kiev, where he found work as an accompanist. In 1919, he worked at the "One-eyed Jimmy" variety theatre in Rostov-on-Don.
Military career
In 1919–1921, Pokrass served in the First Cavalry. In honour of the taking of Rostov by the First Cavalry, he wrote the song which gained national popularity, "Budyonny's March". To his fellow soldiers of the First Cavalry, he dedicated further compositions: "Hey, hey, saddle the Horses", a cantata "Forward" and a military march, "Red Cavalrymen", both with lyrics by S.Minin.
Professional career
Relocating to Moscow in 1923, Pokrass worked in different genres of variety music. He wrote music for theatres of miniatures and a cabaret, accompanied a Gypsy chorus, the Gypsy song performers E.Dobero and O.Vargina. Pokrass tried to overcome the stale character of the variety genre in romances by using lyrics of "highbrow" poetry by Alexander Blok, Igor Severyanin, and others. In 1940, Pokrass became a member of the Communist Party of the Soviet Union. From 1923 to 1926, Pokrass served as the principal conductor and musical director of the Moscow theatres "Oriental Carpets" and "Hermitage". In 1926-1936 he was the principal conductor and musical director of the Moscow music hall. Between 1932 and 1954 he worked in collaboration with his brother, Daniel Pokrass. In 1936 - 1972 he was the artistic director of the Variety orchestra of ЦДКЖ. He composed songs, film scores, and incidental music for the theatre, as well as military marches such as the March of the Soviet Tankmen. After Daniel's death, Dmitry wrote the "March of the Motorized Infantry", "Great City",, "My Small Hometown", "The March of BAM". He also composed music for the stage plays "Red Devilkins" and "Konarmiya", works for the violin, and romances.
