Beijing based pop-punk band Reflector have posted this video from their 15 year anniversary tour. They are very popular on the scene. I saw them at Yuyintang a few years back and the place was crazy filled to the point of danger, with fans you don't see at the other shows.
In this video we see them playing Little Bar in Chengdu and it's unsurprisingly packed and includes crowd surfing and sing-a-longs. The track is 只有音乐才是我的解药 Music is my only medicine (my liberal translation.)
