Siti binti Saad was a pioneering Tanzanian musician in the taarab musical style. Through her music she was also an anti-colonial activist, feminist and Swahili cultural icon of 20th century. She produced over 250 phonograph records throughout her lifetime, becoming the first East African vocalist to release commercial recordings in the 1920s and 1930s. She also added a brand-new dance and pantomime component to taarab music called "natiki," which was inspired by Indian dance. She was a trailblazer as a female performer in the genre during a time when men artists controlled the industry. She performed in a variety of languages, but most significantly in Swahili, in contrast to earlier vocalists who solely sang in Arabic. She sang in cities of the coast of Tanganyika and Zanzibar.
