Chinas alternative music scene is on a massive growth spurt, with loads of new bands and sell-out gigs. But with few labels to support it, festivals and corporate sponsors are payrolling the revolutionLast month, Beijing-based label Modern Sky took its festival to New York for the first time. The Modern Sky festival was a two-day showcase of Chinese talent, including arty synth-pop outfit Queen Sea Big Shark, traditional folk-rock crossovers Secondhand Rose and John Lydons favourite post-punk band Re-Tros.The success of the festival is another landmark in the inexorable rise of Chinese alternative music, but it also indicates clearly who holds the power in the nascent, Beijing-focused scene.
