Things get witchy this week as Brian and Ryan weave a conversation on spell casting, rock n' roll, and badminton with fibers artist Karolina Gnatowski.   Fresh off a Skowheagan residency, Gnatowski is burning a four ended candle with looming exhibitions at DePaul University, Free Range, Terrain, and the here and now, "Changeling" at Julius Caesar. Our conversational arc ties together the topics of witchcraft, spells, poetry, badminton, classic rock, and stand-up comedy. Brian reveals his sporting past, Ryan finds just the right word, and KG admits she's never seen "Top Gun."
