On the hard-driving “Strength to Survive,” one of singer-guitarist Toronzo Cannon's best tunes, Cannon sings about how “real life” is getting in the way of his dreams. He describes himself as a “broken man” who can’t look at himself in the mirror. It’s heavy, emotional stuff and the riveting guitar solos possess a real weight too from the Chicago City Bus Driver who’s became the latest highly rated blues export from the Windy City. He comes to Music Box Supper Club tonight at 8 in support of his latest effort, The Preacher, The Politician Or The Pimp.
