NiziU has dropped a performance video for “Sour Grapes,” a new performance-focused release that arrived on the official JYP Entertainment YouTube channel.
The upload was flagged to the r/kpop community earlier today (October 7), where the clip was shared as a new post. According to the original listing, the video is titled “NiziU(니쥬) “Sour Grapes” Performance Video” and was published through JYP Entertainment’s main channel, @JYPEntertainment.
The post itself carried little extra detail beyond the link: its lone comment was an automated reminder about the subreddit’s 2026 census, not fan reactions to the clip. No official statement about the video accompanied the materials reviewed, and nothing beyond the upload itself was available in the source thread.
Fans can watch the full performance video on the JYP Entertainment channel. Further details about the track’s promotion had not surfaced in the reviewed materials as of writing.
