Estonian composer Arvo Pärt’s Tabula Rasa surprises us for its apparent simplicity yet forceful emotional content. Tabula Rasa features two violins, piano, and orchestra. Linked here is the 4th section.
The composer describes his music as tintinnabuli, or a ringing of the bells. His influences range from neoclassical to medieval chant to Schoenberg and the 20th century minimalists. Attempts to categorize Pärt trend to sacred- or holy-minimalism; his work often contains Christian motivation and text and is rhythmically simple and often mathematically derived. He was born in 1935.
Thanks to @neverett for the recommendation.
