This year’s main stage national headliners are especially strong — Webb Wilder on Friday and Duke Robillard on Saturday — but the Cincy Blues Fest always has a ton of interesting and engaging artists performing throughout the fest’s multiple stages. See Spill It for more details on the event’s many offerings. Tickets are $20 each day (two-day passes are available Friday at the gates for $30), or grab yours early through brownpapertickets.com for a $5 discount. Or you can join the Cincy Blues Society (cincyblues.org), the creators and managers of Cincy Blues Fest, to receive an even deeper discount. Music starts at 5 p.m. Friday Aug. 10 and 4:30 p.m. Saturday Aug. 11. Visit cincybluesfest.org for full details.
