Blue Note Records was founded in the 1930s and has played a vital role in the development of jazz for more than 60 years. Important works by some of the greatest jazz musicians in history — John Coltrane, Miles Davis, Thelonious Monk, Art Blakey, Wayne Shorter, Freddie Hubbard, and many others — were recorded on the Blue Note label. The company’s founders, Alfred Lion and Francis Wolff, both loved jazz (especially jazz with a bluesy element) and had true respect for the musicians with whom they worked. Featuring appearances by many artists — and memorable music recorded in the Blue Note studios throughout the years — this documentary explores the evolution of the genre, while telling the story of a company that marked an important period in music history.
