César Antonovich Cui (Jan. 18, 1835 - March 13, 1918) was a Russian composer and music critic, and also an army officer, and military academic. He's widely known for being a part of the "The Five" (also known as the Mighty Five, or the New Russian School), along with Mily Balakirev, Modest Mussorgsky, Nicolai Rimsky-Korsakov, and Alexander Borodin. 

Growing up, Cui was prepared for a life in the military, much like his father. He went to technical and engineering school, and ended up teaching about fortifications; his writings were used in textbooks, and he taught military academies in St. Petersburg. Music was more of an avocation for Cui, growing up and later in life. He took piano lessons as a young boy, and began composing when he was 14. When he met Mily Balakirev, in 1856, his life took a turn, and he became more serious about music composition. He also was busy as a music critic (eventually writing around 800 articles.)

Cui wrote for various genres, but was particularly drawn to vocal works, including works for children. Everywhere Snow is from his Seven Choruses, which is an unaccompanied setting for children's choir, with the libretto based on a poem by writer Ivan Belousov.

Romantic in style, this movement is only around two minutes, and is a straightforwardly written work, but the unaccompanied setting (and sung by children) imbues it with a sense of novelty and innocence.

Here's a recording of this sweet work for you to enjoy!
