The Midnight Jazz Cats bring their Boise swing sound to The Sapphire Room at The Riverside Hotel on August 14, with special guest Jillian Kates, a Brooklyn-based musical theater artist. Expect the kind of cool retro jazz that fills a room with that golden-age feeling—whether you're a longtime jazz fan or just looking for a sophisticated evening out. The Sapphire Room's intimate setting pairs well with the combo's energy. Doors open at 6 p.m.
