K-pop group NEXZ released the first concept photos for their fourth mini album 'SAUCIN'' on their official SNS channels on August 10, with an official release scheduled for August 24 at 6 PM. The seven members—Tomoya, Yuu, Haru, So Gun, Seita, Hui, and Yuki—showcased mature and refined visuals in a mysterious manufacturing space, creating intrigue about NEXZ's unique 'secret recipe.' The teaser images feature unexpected editing techniques including pixelated faces, low-quality visuals, and exaggerated perspectives that enhance the mysterious atmosphere. The album contains six tracks: the title song 'SAUCIN'' and additional tracks 'LOCO,' 'APPETITE,' 'UPGRADE,' '20 NOW,' and 'ALIENS.' Members Tomoya, Haru, and Hui participated in writing and composing 'APPETITE,' while leader Tomoya also contributed to writing and composing '20 NOW.'
