MIDI — China's longest-running outdoor music festival — was hit the hardest by this season's de facto ban on large-scale public gatherings. 2015 was the first year since the festival was launched by the Beijing Midi School of Music in 1997 that it wasn't held on its home turf. They couldn't sort a permit for Shanghai, either.

Luckily, they had a fallback: Camp Midi, a theme park located next to the massive Taihu Lake near Suzhou. I went to the festival this year expecting "Camp Midi" to be a euphemistic name for a huge plot of grass, but no: it's a bona fide amusement park. Tilt-a-whirls, merry-go-rounds, miniature mock-European villas, an "American Barbecue Restaurant", the whole nine yards.

For this ad hoc festival, Midi constructed their standard four-stage spread, and the music lovers came, and the music lovers camped, and there was plenty of rock'n'roll and mud for all. Here are some photos we've culled from the deep archives of "social medias we can't ignore anyway" in case you missed out*:
