Red Velvet has completely sold out the two shows of their concert.
The girls will be at the Olympic Hall on August 18th-20th for their first ever concert 'Red Room'. Originally, the girls were scheduled only for the 19th and 20th, but their concert was in such high demand that an additional date on the 18th was added.
