SM Entertainment's NCT JNJM (Jeno and Jaemin) is making a surprise debut with their first mini-album 'BOTH SIDES' on February 23rd. The two members, who are the same age and have grown together since their trainee days over 10 years ago, have accumulated strong chemistry and extensive history through their activities in NCT and NCT DREAM. This unit is characterized by the contrasting charms of the two members, where 'differences become strengths.' Jeno, who leads with powerful performances and stage presence, meets Jaemin, who adds a relaxed charm on top of solid skills, creating a new color combining intensity and delicacy, direct energy and leisurely atmosphere. The mini-album 'BOTH SIDES' contains 6 tracks including the title song of the same name. The title track 'BOTH SIDES' is a hip-hop dance song that blends witty vocals and rap over sensational sound design and fluid drum beats, conveying a cheerful aspiration to captivate each other with two different charms. The album also features diverse musical spectrum including 'I.D.O.L.', an upbeat pop song based on Miami bass, 'HASHTAG', a sensual hip-hop song that reinterprets late 2000s southern hip-hop sounds with a modern twist, 'What It Is', an ethereal R&B pop track, 'sexier', a provocative hip-hop dance song, and 'WIND UP', an energetic hip-hop track. The entire album centers around the keyword of 'duality,' harmoniously depicting moments when Jeno and Jaemin reveal their individual colors and moments when they blend together in balance. This message has been visually maximized through teaser content released since the 7th.
