Born Lê Nguyễn Nhật Quang, KK Kasper grew up in Vietnam's capital, Hanoi, and began "seriously" composing music on November 10, 2023. In 2022, KK formed a duo with his friend, Lạch Vĩnh Thu and released the album "VÔ VÀN" under the name KZ. Following the publication of the record, which combined many various forms of music, public exposure enabled them to perform at a variety of shows. After much deliberation, he took the name KK Kasper. By that, with Linh Vep (was Lach Vinh Thu) and a young talented producer LostInSpace, they created "Sáu Thứ Tối", reaffirming their commitment to the music career.
