Fresh on the heels of last month's much-appreciated Antidote Electronic Music Festival in Zhujiazhao, "Electro Grass" will be featuring a full roster of mostly local and a few international DJs and electronic acts. Tickets are really reasonable at 60rmb pre-sale (available at The Source) or 90rmb at the door. Runs from 8pm until 4am. Check the full line-up here
Note: The event is at the Donghu Hotel, opposite the Element Fresh, the entrance is on the corner of Donghu Lu and Huai Hai Lu (there's another Donghu Hotel further down the road towards Xinle Lu).
