Yo Gabba Gabba. Coachella. Yes, the two coexisted. Visual proof below. It's not entirely surprising as DJ Lance Rock was scheduled to be at the Sahara stage/dance hall, but the presence of the whole YGG gang and an event which has never made any move towards kid-inclusion is either a jump-the-shark moment or some sort of tipping point into mainstream acceptance. They're not necessarily mutually exclusive, but check out the number of folks in the front few rows lifting up their cameras to record the thing for posterity. My money's on "mainstream acceptance," though one could argue they already had it.
And they were elsewhere at Coachella this weekend...
