Will this man be lounging backstage at Merriweather Post Pavilion in September? (Joel Salcido For The Washington Post)

And, yes, we do know that there will be another Virgin Mobile FreeFest at Merriweather Post Pavilion in 2011. That’s all we know as of now. Well, also that you will be able to buy food from Merriweather’s new Jean Valdez’s Columbian Burrito Factory. Now if you want to down a burrito at an all-day music festival … that’s for you to decide. Onto the first batch of predictions...

TV on the Radio

Perhaps you saw the indie rock bigshots recently announced a joint September tour with Canadian collective Broken Social Scene. And perhaps (like our ace photographer Kyle Gustafson ) you noticed a weird gap in between their shows on Friday, Sept. 9 in Philadelphia and Monday, Sept. 12 in Charlotte. Does that mean there will be a Sept. 10 or 11 stop at Merriweather? Last year’s fest was on Sept. 25; the year before on Aug. 29. The timing is right.

Foo Fighters

The band almost seems too big for the festival at this point. Yes, they were a headliner in 2008 but that’s when people still paid big bucks for tickets and the show was a two-day colossus at Pimlico. Compared to the likes of recent headliners Blink-182, Weezer, LCD Soundsystem and M.I.A., the Foos are simply on another level. Yet you can’t deny the band’s strong ties to all things 9:30 Club/I.M.P. related and the lack of a D.C.-area show since “Wasting Light” was released.

More guesses after the jump...

Big Boi at FreeFest — wishful thinking or smart prediction? ( Kyle Gustafson/For The Washington Post)

Best Coast
Just a wild guess on this one based on nothing except the fact that songs such as “Boyfriend” and have some mindless summer fun. Best Coast played 9:30 Club last year and will be at Merriweather this weekend opening for the Decemberists, so those connections are solid.

Titus Andronicus
Another band that seems to be doing the festival circuit this summer, including a just-announced date at North Carolina’s Hopscotch Festival, which is happening on the same presumed FreeFest weekend. This is a band that is can handle a big stage and bigger crowd and would be a perfect fit for the non-pavilion stage in the middle of the day.

Other guesses: Santigold, Cut Copy, Death From Above 1979

Feel free to chime in with your own predictions. If they’re on point, we just may steal them for our next post on this topic!
