 This evening at the Hotel Tavern Inn, bass player Victor Dvaskin plays duets, often with a guitarist, and more duets tomorrow evening at the Hotel Tavern Inn, usually led by a guitarist. They used to list their stuff online, but they don't anymore, so I'm not sure who's playing when. But music Sundays and Mondays from 6 to 8.30 at the Hotel Tavern Inn, 1739 N Street, Northwest, downtown.
