Ever hear of Acquire the Fire Battle Cry?

Hey everyone! I just got back from and amazing weekend in Detroit at Ford Feild with my youth group! There was 35,000 people there! It's just saying we are not gunna take the current situations in the world, we want a change for our next generation! There were like 6 bands playing there. Don't know if you heard of them they are Christian bands...Pillar, Crossmovement, Michael Gungor (or something like that), KJ-52, TOby Mac, and Delerious...ust curious as to how many have heard of this..it was in Tampa and San Franscisco as well!
