Mnet is showcasing a new survival project in 2024, aiming to create a new type of vocal boy group. 

The upcoming vocal boy group survival, 'Build Up', seeks to "build" the most charming vocal quartet out of 40 currently active male K-Pop idols. The teaser begins with MC Lee Da Hee stacking blocks up in various formations, describing the premise of the program. The teaser then showed a "silhouette" teaser of all 40 contestants, inviting global K-Pop fans to guess at the identities of the veiled faces. 

Furthermore, viewers can go to Mnet Plus to listen to the "voice silhouette" teasers of all 40 contestants, and create their most preferred formations based on the 

teasers. 

Mnet's 'Build Up' is expected to air on January 26 at 10:10 PM KST.
