She was born in Chattanooga, Tennessee. Raised on the road in a show-business family, she learned to play cello, bass, banjo, violin, mandolin, harp, accordion, clarinet, trumpet, and saxophone by the time she was 15. She also sang and danced.
After focusing on the trumpet, she quickly became so famous at the instrument that she was named "Little Louis" after Louis Armstrong, who called her the world's second best jazz trumpet player besides himself. Contemporary critics Krin Gabbard and Will Friedwald have commented on her approach to playing like Armstrong. Gabbard said she developed a "distinctly Armstrongian style" and Friedwald said she "mimicked" Armstrong. In a 1928 performance in Chicago at the Sunset Café, Snow played the trumpet, sang. Then seven pairs of shoes were placed in a row at the front of the stage, and she danced in each pair for one chorus. The dances and shoes to match were: soft-shoe, adagio shoes, tap shoes, Dutch clogs, Chinese straw sandals, Turkish slippers, and the last pair, Russian boots. "When Louis Armstrong saw the show one night, he continued clapping after others had stopped and remarked, 'Boy I never saw anything that great'." She played concerts throughout the US, Europe, and China. From 1926 to 1929 she toured with Jack Carter's Serenaders in Shanghai, Singapore, Calcutta, and Jakarta.
Her most successful period was in the 1930s when she became the toast of London and Paris. Around this time she recorded her hit song "High Hat, Trumpet, and Rhythm". She performed in the Ethel Waters show Rhapsody in Black, in New York. In the mid-1930s she made films with her husband, Ananias Berry, of the Berry Brothers dancing troupe. After playing the Apollo Theater in New York City, she revisited Europe and the Far East for more shows and films.
According to a jazz radio show that aired 10/28/2017, she said she was arrested in Europe, apparently going to jail for theft and illegal drugs. While later touring through Denmark in 1941, she said she was arrested by Nazis and probably kept at Vestre Fængsel, a Danish prison in Copenhagen that was run by the Nazis, before being released on a prisoner exchange in May 1942. It was rumored that her friendship with a Belgium police official helped her board a ship carrying foreign diplomats. According to jazz historian Scott Yanow, "she never emotionally recovered from the experience". She married Earl Edwards. In the 1950s, she was unable to regain her former success.
