This looks really good. Boogatti Records and Dragon Adventures are teaming up to throw a rave at Playa Maya Water Park in Songjiang. They've booked two really solid Russian producers, Pixelord and 813, plus lots of local talent like Conrank, Yeti B, Love Bang, Peanut Butter & Jellyfish, and more. Tickets are 220rmb early-bird, coming soon on Dragon Adventures, or 280rmb there. The water park is super fun by itself, so this should be great. Goes all day. Park is about 40 minutes from downtown by cab. If post-poned, will get moved to the next day, which is a public holiday.
