NCT 127 sequentially released 6 episodes of the teaser 'Call 127' for their 7th regular album 'BLINGY' through their official YouTube channel on the 3rd and 4th. The released video unfolds the narrative of members who previously worked as 'Seoul's Problem Solvers' before naturally scattering and reuniting. Members including Haechan, Jaehyun, Yuta, Johnny, and Taeyong appear as characters with unique settings such as a comic book store customer, negotiator, and detective. The teaser features the included track 'I mean, It's about time,' a pop genre that harmonizes string performances with 1990s hip-hop drum beats, conveying a message of reflecting on the group's past 10 years and continuing together. NCT 127's 7th regular album 'BLINGY' will be released on the 24th.
