The Exploding Star Orchestra is Rob Mazurek’s vehicle for blowing minds and reshaping worlds. For more than a decade and a half, the multi-instrumentalist has guided the variably configured big band through appearances on three continents. Its first performance in his former hometown of Chicago in more than five years determined to be more than just a concert. With support from the city’s Experimental Sound Studio and International Anthem, the Exploding Star Orchestra not only played music from the new Lightning Dreamers LP, but Mazurek and Co. also showed the processes behind its creation.
