Basia Trzetrzelewska [ˈbaɕa tʂɛtʂɛˈlɛfska] (born September 30, 1954) is a Polish singer-songwriter and record producer. She established a successful international recording career featuring characteristically Latin-flavoured jazz-pop crossover songs during the late 1980s and early 1990s and the late 2000s and 2010s, particularly in the United States, the United Kingdom, France, and Japan. She is noted for possessing a wide vocal range, approximately three octaves that span from contralto to soprano tessituras, as well as her singular jazz-influenced stylings and multi-layered harmonies.
