The Chicago Blues Festival kicks off this weekend. The city is known as the blues capital of the world and why not, we have a rich history when it comes to the genre. That history is captured in the book, Exploring Chicago Blues: Inside the Scene, Past and Present. We talk with the author Rosalind Cummings-Yeats. We get you in a Blues mood with the smokin’ hot sounds of Delmark recording artist Toronzo Cannon. His latest album is John The Conquer Root and his previous album is Leaving Mood.
