Rancid were added to the May 19th Black & Blue Bowl at Webster Hall. Advanced online tickets are sold out, but the event is not. You can still get them at shops and at the door (they always leave some for walk-ups). Rancid also play Northern Lights in Clifton Park one day earlier. Tickets are still on sale for that. More Racid tour dates at their site.
