Hyunjun Chang (BLKCUBE) is a composer and producer based in Seoul, working at the center of the Korean music industry. Raised on the sounds that shaped K-pop, he has spent the last 7 years writing and producing for artists including XIA Junsu (TVXQ), Onew (SHINee), (G)I-DLE, and more.

At The Debut: Seoul, every session is run by him directly — the same ears, the same process, the same standard he brings to every commercial release.
