Four stages, twenty-seven seconds, no warning. MBCkpop put the run up at five in the afternoon Seoul time on August 6, opening with Xdinary Heroes alone on 'Beautiful Life' — four minutes twenty-nine seconds — and following five seconds later with the same group credited alongside KAO(Virtual YB) on 'iNSTEAD!' and 'Rebellion', five minutes twenty-seven.

RIIZE came three seconds after that. 'Fly Up' runs three minutes six seconds, and nineteen seconds later 'Bag Bad Back' closed the batch at three minutes twenty-four. Observed shortly after posting, the four stood at 132, 191, 267 and 360 views in the order they went up — 950 between them, with 159 likes and 10 comments.

The descriptions say almost nothing. Each is a row of hashtags and a rights line: the collaboration carries #KAO, #카오, #YB, #윤도현, #XdinaryHeroes, #엑스디너리히어로즈, #iNSTEAD, #Rebellion and #버추얼라이브페스티벌, while the RIIZE pair swap in #RIIZE and #라이즈 with a tag per song. Every one ends on ⓒ MBC&iMBC and a reservation of rights that names AI training among the uses it covers. No date, no venue, no line-up appears anywhere.

So what we can say is what the posts say: a festival called VLF — 버추얼 라이브 페스티벌, Virtual Live Festival — and four stages from it. Our record holds 1,049 MBCkpop posts and this tag has never appeared on any of them before today.
