Metro Scores AWESOME Lolla Aftershow: Dave Grohl, Josh Homme, And John Paul Jones?

Now THIS is a Lollapalooza aftershow! If you peep the top of the official Lollapalooza 2009 Aftershows page, you'll see a mysterious set of symbols are playing at Metro on Sunday night. We're guessing this will be the public's first chance to see the Foo Fighter's Dave Grohl, Queens Of the Stone Age's Josh Homme, and Led Zeppelin's John Paul Jones play their new material. Tickets go on sale Thursday morning at 10 a.m.
