Regular visitors to the Chicago Blues Festival know Zora Young, 67, from Mississippi. Fans of Pinetop Perkins [1913-2011] and Hubert Sumlin [1931-2011] know New York harmonicat Mike Markowitz and his Tornadoes as the touring and recording band of those two late legends. On Friday Night, Zora, Mike and the boys get down. Period. This harmonica/guitar/bass/drums/saxophone/trumpet band has been putting out solid blues records since 1990. But here, they throw the rulebook out the window and burn it.
