Here is an album dedicated to teaching and comprehensive on the blues Blues "Delta". The Blues, born in the years 20-30, which is the result of a wave of black migration from young musicians to try their luck in the north of their beloved country; including Chicago and will naturally become the capital. Many setbacks, many turpitude expect these candid and brave musicians who know that success exists for any Black living in Mississippi, Alabama or Texas (and other states). But these lovers of music, which can be drawn Big Joe Williams, Sonny Boy Williamson, Bessie Smith as much as for Muddy Waters, Willie Dixon and John Lee Hooker and BB King, have pierced or not in Blues music, a lot of them meet the devil lurking in the corners, which introduces and retains the vices (alcohol, drugs, violence, sex ...). Despite highly questionable behavior, the precursors of Blues touch us deep in our heart, our soul, through their tortuous and difficult path, which sweated through their songs, their cries, their unparalleled riffs . In short, an essay that goes to the roots of the protest music and off-system: often misunderstood and rejected ... Unfairly. The Blues is indeed much more than music: it is a means of expression, a long tunnel of emotions.
