刘心宇，生于北京。北京实验音乐演出组织“燥眠夜”和“密集音乐节”的常客。08年启动自己的吉他独奏计划， 出于对吉他回授与共振的痴迷，他首次演出便用30分钟不停断的大音量吉他啸叫吵走了场地内每一名观众。近年来他将对回授的注意力逐渐转移到调音台反馈上，告别了大音量噪音，更加关注细微的声音。现主要使用无输入调音台和他自制的声音装置去探索来自微观世界的声响。他同时也是Sleeping Dogs和致命摇篮死乐队中的一员。
Liu Xinyu, born in Beijing. Regular participant in Beijing's Zoomin' Night and MIJI experimental music performance series. In 2008, he started a project of solo guitar performance. The first time he performed, due to his enthusiasm for feedback and resonance, he succeeded in expelling every single audience member from the room with 30 minutes of non-stop, earsplitting guitar noise.
In recent years, Liu Xinyu has gradually shifted his attention from guitar to no-input mixer as a source of feedback. Instead of earsplitting noise, he pays more attention to subtle sound. Currently, he mainly uses no-input mixer feedback and self-made sound installations to explore micro sound worlds. He is also currently a member of Beijing bands Sleeping Dogs and Deadly Cradle Death.
