Christopher Chahn Bahng, known professionally as Bang Chan, is a Korean-Australian singer, rapper, songwriter, and record producer under JYP Entertainment. He is the leader of the boy group Stray Kids and its sub-unit 3Racha. Bang Chan played a pivotal role in forming Stray Kids by selecting trainees, naming the group, and designing its logo. The survival show Stray Kids documented this process, focusing on whether Bang Chan's team would debut together, unlike typical survival shows where agency management determines the lineup. Since February 2023, he has been a full member of the Korea Music Copyright Association (KOMCA). Beyond creating music for Stray Kids, he has composed for TV series like Pop Out Boy!, Tower of God, and Re:Revenge – In the End of Desire, as well as films including Doraemon: Nobita's Sky Utopia and Deadpool & Wolverine. Bang Chan has also written songs for artists such as JO1, Yao Chen, and Show Lo, and collaborated with Alesso, Sky-Hi, Tiger JK, Lil Durk, and Japanese singer LiSA.
