It might be the case that Blink-182 is playing under Linkin Park and it's not a co-headlining situation. Then again they will probably both play an hour so I don't know. Also, looks like Blink-182 will be opening up for Linkin Park at Southside/Hurricane I'm assuming based off of this lineup. I feel like this is the only type of show where you would ever see them play on the same day, wish I could fly out and go to download!
