As hinted earlier this month, the 2013 edition of Virgin Mobile FreeFest will indeed be taking place Sept. 21 at Merriweather Post Pavilion in Columbia, Md. The show’s booking company, I.M.P. Productions, made the formal announcement this morning.

The festival’s lineup remains a mystery, though, so it’ll be a bit longer before this year’s crop of pushy, tipsy teenagers find out what acts they’ll be awkwardly twerking to in the Dance Forest. But Virgin Mobile FreeFest might feature the chillwave recording artist Ernest Greene, better known as Washed Out, who tipped the festival’s date when he listed it on his website.

Then again, Washed Out might not be on the billing anymore. The date has been conspicuously scrubbed from his tour page.
