<P> The Chicago blues is a form of blues music indigenous to Chicago , Illinois . Chicago blues is an electric blues style of urban blues . Urban blues evolved from classic blues following the Great Migration , or the Great Northern Drive , which was both forced and voluntary at times , of African Americans from the southern United States to the industrial cities of the north , such as Chicago . Muddy Waters directly joined that migration , like many others , such as in Florida , avoiding the more harshly southern Jim Crow laws . Bruce Iglauer , founder of Alligator Records stated that , `` Chicago blues is the music of the industrial city , and has an industrial sense about it . '' Additionally , recognizing the shift in blues , Chicago blues singer and guitarist Kevin Moore expressed the blues transition stating , `` You have to put some new life into it , new blood , new perspectives . You ca n't keep talking about mules , workin ' on the levee . '' Chicago blues was heavily influenced by Mississippi bluesmen who traveled to Chicago in the early 1940s . The development of blues , up to Chicago blues , is arguably as follows : Country blues , to city blues , to urban blues . Chicago blues is based on the sound of the electric guitar and the harmonica , with the harmonica played through a PA system or guitar amplifier . </P>
