NCT is a powerhouse group, split into various sub-units that portray different concepts and identities. While there's some overlap between genres and members, each unit possess their very own musical color that makes them distinct to the rest. Since their inception, they've primarily focused on group/sub-unit activities to promote and expand the NCT name. However, in recent years, various members have begun to work on their own music and have started their very own solo career. This list includes members TaeYong, Ten, DoYoung, JaeHyun, and Yuta - but now, NCT's Mark is the latest to join the NCT soloist club.

While Mark has dropped numerous singles from the emotional 'Child' to alt-rock '200', "The Firstfruit" marks his first full solo album release. Containing 13 tracks, the album signals the start of a new chapter in the idol's career as he bares all for everyone to see. For NCTzens who have followed Mark's story since debut, it comes as a sweet moment of victory as they see one of their favorite idols finally don on the mantle of soloist after years of determination and hard work.
