High-voltage action

Thirty-something moms push strollers through crowds of colored-hair, tattooed 20-somethings. Dads in jeans and T-shirts chill out with beer in hand while kids sip cola while playing on their skateboards. Everyone cheers as loudly as the hard-core metal fans.

Arguably, the two Chinese music festivals most responsible for transforming the Chinese rock music scene over the past decade are Midi and Modern Sky.
