American music is a wide plectrum that grew out of the musical encounters of immigrant traditions. Blues, jazz, Cajun, gospel and bluegrass all come from the cultures that met in America and new exchanges and new musical languages continue to appear. Through the artistry of people like Frank Hutchison, Memphis Minnie, Howlin' Wolf, Louis Jordan and Eddie Cochrane, the landscape changed beneath our feet. Let's follow the arc of change with such songs as "Stackalee," "Come On in My Kitchen," "Born Under A Bad Sign" and "Summertime Blues."
