Eric Jackson, who has been heard nightly on WGBH 89.7 FM for more than 20 years, discusses the rise of this beloved and uniquely American music form in the wild decade of the 1920's. Jackson, host of WGBH's Eric in the Evening, has been called the dean of Boston jazz radio. Using Buddy Bolden as a starting point, Jackson highlights the changing instruments in the early jazz band and discusses stylistic changes in the music through piano styles like ragtime, stride and boogie woogie. He underscores the differences between what is called New Orleans jazz and the styles popularized in Chicago in the late 20s. Jackson reviews the roots of the big band by looking at Fletcher Henderson and Don Redman's pioneering work.
