Born in 1997, Xu set out performing and producing harsh noise under the alias “Berserk” since 2015. Initially, he focused on playing rough feedback from handmade instruments and synthesizers before carrying on specializes in no-input effects. Influenced by Japanoise, Death Metal, Hardcore Punk, his live performance is known for highly intense physical energy and massive volume. In 2017, he turned to combining various equipments including no-input pedals/mixer and shortwave radio to session with free improvisation musicians and folk narrator. Different to Berserk’s harsh noise approach, his works as Chia-Chun Xu emphasize more on the interaction between sounds, space, and the others. Besides working on his projects, he also runs the music label, MKUltra Productions, promoting Taiwanese and worldwide noise and experimental musicians.

(Z)erpents是以臺裔美籍的吉他手Paul Lai以及台北最狂的鼓手Joseph Mauro為軸心的自由即興音樂組合，每次演出搭配1-3名不同風格的樂手融合成不同風格的演出。 其團體選擇合作對象標準只有一個，就是音樂之於該名樂手要有如好奇心之於貓一般的關係，樂手必須無懼地面對即興時可能的失敗，並且趕於演奏時展現自己的風格。 也因此(Z)erpents的音樂風格並沒有主導的方向，時而自由爵士(free jazz)，時而噪音(noise)，時而是綿延的嗡鳴(drone)，對可以透過下方連結收聽他們於Future Proof發行的專輯 《Black Mold and Hot Springs, Taipei》
