On September 21st, SM Entertainment said that Mark will be in charge of curating and rapping for Xiumin's debut solo album. A new jack swing tune with a 90s sensibility and a contemporary vibe is called "How We Do."

Mark will once again take part in Xiumin's song for the first time in five years following the release of the song "Young & Free" on SM Station in 2017. After ten years since his debut, Xiumin is soon to release his first solo album, titled "Brand New." The agency stated that Xiumin's style was an expression of the musical sensibility of the 1990s and the early 2000s and that five new songs, including the title song of the same name, were recorded.

EXO's Xiumin appeared in the most recent teaser photos sporting a beige corduroy jacket and matching slacks, and he looked dashing as always. He was observed moving across a blank surface surrounded by azure waters and the sky! Mark is a Korean-born Canadian rapper, singer, and dancer. In 2016, SM Entertainment said that Mark would join Taeyong, Taeil, Yuta, Jaehyun, Winwin, and Haechan in the second sub-unit of NCT, known as NCT 127. With the extended play "NCT #127" and title single "Fire Truck," NCT 127 made their formal debut. Mark became a part of NCT Dream, the third sub-unit of NCT, which also included Renjun, Jeno, Haechan, Jaemin, Chenle, and Jisung. On August 24, 2016, the group made its formal debut with the song "Chewing Gum."

Mark's participation in SuperM, a supergroup formed by SM Entertainment and Capitol Records, was officially announced in 2019. In October of that year, the group started advertising in the American music industry. On October 4, 2019, SuperM's self-titled first EP was made available, featuring the tune "Jopping." The debut solo album by Xiumin, titled "BRAND NEW," will be made available on various music websites on September 26 at 6 PM KST (2:30 PM IST) and as an album the same day.
