Chorale for One / Urszula Dudiak / Future Talk / Inner City Records 1979:
 

Urszula Dudziak was born October 22, 1943 in the Straconka neighborhood of Bielsko-Biala Poland. Voted “jazz singer of the year” by the Los Angeles Times in 1979, Dudziak is known for her five octave range, revolutionary use of electronic devices to process her vocals, and for using sounds, tones and scatting rather than words.

She frequently worked with leading contemporary musicians, including Archie Shepp and Lester Bowie, Bobby McFerrin, Norma Winstone, Sting, Michelle Hendricks, and Lauren Newton. She often worked with Gil Evans in the 80s, recording on five Gil Evans releases.

Dudziak studied piano and began to sing after hearing Ella Fitzgerald, taking two years of vocal lessons. She quickly became the leading jazz vocalist in Poland. She met and later married Michal Urbaniak, and recorded several releases with him. In the late 60s they began to tour overseas and in the 70s settled in New York.
