Holler Grove plays 5 Walnut Wine Bar on Saturday, August 29 at 8:00 PM. Doors open ahead of showtime; check ticketing for age policy and cover. This downtown Walnut Street spot holds maybe 75 people tops, so you're basically sharing a living room with the band while sipping wine and grabbing cheese boards from the connected shop next door. Seating is tight and those window bar perches go fast, but that's the whole appeal when acts roll through up to seven nights a week with no cover.
