Chicagoan Joe Rauen’s approach to music is a little weird, because, well, the instruments he plays are weird. Learn what drove this Berklee-trained musician to embrace the odd, including a suitcase bass, a tennis racquet banjo, and an electric shovel guitar in this Backstory segment from Larry Potash. Backstory airs Saturday nights at 6 on WGN-TV. Check out the Backstory podcast at WGNtv.com/Backstory via Stitcher, iTunes, Google Play, or wherever you get your podcasts.
