So I flew up to Chicago to do Paramore's new press photos, you can't see any of those yet (you will in the next months), but here's the photos from their October 30th Halloween show. Also, you can see their halloween costumes from actual Halloween which was a day off they spent in Chicago as well.

Josh and Hayley before the show.

Before the encore they changed into costumes.
Hayley was Darth Vader, Zac and Taylor were Kid N Play from House Party (I'm just saying that I dont think theyve ever even that movie), Josh was a ninja, and Jeremy was Hulk Hogan.
