Hong Chulki(Hong is the family name) was born in 1976 and he lives in Seoul, South Korea. In 1996 he formed a band called 'Mani Mukgo Himne' with his friends. However he was so into guitar noise and feedback that he brought up the idea of forming a noise project with Choi Joonyong. In the early days of Astronoise, Chulki played guitar making only howling feedback sound. Now equipments he uses are especially turntables, mixers, broken MD players, laptop, CD player. Still it's all about feedback and amplification. When Astronoise's first demo tape 'Feedback Composition No.1' came out, he also released his solo works of guitar soundscape called 'Lightyear'. He has also led bands like Puredigitalsilence and Automatic Hand-dryer. He currently performs as a member of Astronoise, Seoul Frequency Group and as himself exploring different ideas with other musicians. He has released three solo albums(including one web release). 'No Silence' is made with mixing board feedback and 'Surface & Feedback'(released by Manual) and 'without cartridge, with cartridge' are made with turntable.
