It's no easy task summarizing the history of recorded jazz from 1917 to the present, but Ken Burns does a fine job of accomplishing just that on this five-disc overview of the music. From the Original Dixieland Jazz Band's "Livery Stable Blues" to Cassandra Wilson's "Death Letter Blues" this well-chosen survey documents the amazing evolution of our national art form. From blues to New Orleans-style to swing to bop to modern to free jazz and on to contemporary sounds, as well as many of the tangents within that broad spectrum, each idiom gets its due. The greatest musicians and some of their greatest musical moments are here: Louis Armstrong's "West End Blues," Duke Ellington's "Cotton Tail," Benny Goodman's "Sing, Sing, Sing," and Miles Davis's "E.S.P.," are just a handful of the brilliant examples of jazz at its best. For those who love the music and those who are just getting their first taste of it, this box set is essential.
