On Tuesday, September 24th, Madison bassist Joshua Cohen joined WORT’s Peter Haney in Combo B to play his transcriptions of Bach live on “Back Porch Serenade.” If you frequent farmer’s markets in Madison, you have probably seen Cohen playing an eclectic array of music on a six-string electric bass. His two-handed “tapping” technique allows him to coax polyphonic music out of an instrument generally played monophonically. On Friday, October 18th he will headline the Waupaca Bach Festival, playing his transcriptions of Bach at the 22 Lakes Brewing Company. Later this Fall he will tour the West Coast before returning home to Madison. Here locally, he plays with such jazz acts as Bad Philosopher in addition to his street busking. After clashing with the City of Madison over its rules for outdoor performances of amplified music, Cohen is suing the city of Madison, arguing that city ordinances amount to an unconstitutional restriction on musicians’ freedom of speech. He is represented in this effort by noted local attorney Jeff Scott Olson. The suit, previously covered by Dylan Brogan of the Isthmus, goes to trial late this year or early next year. Musical selections heard in the interview include the fourth Two-Part Invention, the Prelude, Allemande, and Courante from the first solo cello suite, and the Prelude and Fugue No.2 in C Minor from The Well-Tempered Clavier.
