This is a summary presentation of multimedia concert shows entitled "History of Jazz & Blues", by the band Rui Azul Index, as a chronologic journey through the Jazz eras of XX century. Here we can hear assembled excerpts from some recorded live tunes, and watch samples of the video-slide projection that runs along with the live show. All performances are presented by a Crooner that previously comments some of the characteristics and socio-cultural evolvements on several Jazz styles/currents, from past to present days.
