By day, Mitch Rothstein is a member of the math faculty at UGA. By night, he is among the most accomplished jazz keyboardists in our town. On most Mondays, you can find him at Ciné between 6 p.m. and 8:30 p.m., sitting in at the weekly jam session. I’m headed over there in a few minutes, and I hope Mitch shows up. I love listening to his music.
