How the music of the blues lives as much in the music as in the real lives of its artists who sing it. Two brothers create a style of music called Southern Rock, that blends genres and styles creating a unique sound of jazz, blues, country and rock and roll. In such a short period of just a few years, the Allman Brothers Band produced some of the best recordings in rock history, and one live recording at the Filmore East that has been called the greatest live recording maybe ever.
