The Fan Meeting Ended and a Video Was Left Behind — 26 October, and Next Spring

In three lines

• RIIZE held their third-anniversary fan meeting 'Ch. RIIZE : ON AIR' at Inspire Arena in Incheon on 12–13 September.
• A prologue single on 26 October and a second studio album in spring 2027 were announced today.
• The plan surfaced before any press release, in a video played on site right after the show on the 13th.

The show was built around the theme of a special broadcast channel: a behind-the-scenes talk corner, a random dance battle, solo stages framed as a trainee evaluation, and VCRs shaped like news bulletins and commercials.

What the team said: "It suddenly reminds me of our debut showcase, and I'm glad we can be here with more BRIIZE than we had then… It's already three years but it's also only three years, so I'm looking forward to everything we'll do together with BRIIZE. I hope we're still seeing each other at the 300th anniversary."

That's the last of the numbers. Now, the music.

'Sunburst' Throws Away Its First 15 Seconds

We measured 'Sunburst', the video embedded above. It's three minutes 59, and the first 15.6 seconds are not music.

The overall level sits at −42dBFS, effectively silence, and 30–110Hz is basically empty. The energy is clustered in 2–8kHz. It's ambience and effects from the video's scenes. A short spike passes by around eight seconds.

At 0:15.64 the song crashes in all at once. The ten milliseconds before it cut to complete silence, and then a broadband hit arrives. It climbs more than 20dB in ten milliseconds. That's an opening that starts with a blow, not a fade.

But it doesn't give you everything at once. From 0:15.6 to 0:22.9 the arrangement is still half-built, with the low end more than 10dB below where the chorus will put it. Then at 0:22.5 the low end drops out entirely for 0.4 seconds, and at 0:22.95 the kick returns and the full arrangement begins.

From there the kick lands at regular 0.458-second intervals. About 131BPM.

The same device repeats throughout. At 0:36.9 the low end empties and returns at 0:37.6 (entering the first chorus); at 2:48.9 it empties again and hits back at 2:49.5. Empty half a second, then one blow — that's the grammar of this song.

A Ten-Second Gap

The most striking part is the ending.

At 3:26.25 everything cuts. Then from 3:27 to 3:36.8, the same −41dBFS scene audio as the opening runs for ten seconds. Ten seconds of silence in a four-minute video is long. Long enough to think it's over.

At 3:37.34 it comes back. From −42dBFS to −4.5dBFS in forty milliseconds. It's the biggest moment in the video. Those ten seconds of nothing were assembled for this single blow.

And the closing stretch is narrower in stereo than the choruses. The sound they'd been spreading wide all song gets gathered into the centre for the finish. A fade begins at 3:49, and after 3:53 there is complete silence.

The Order the News Arrived In

This plan didn't come out through a press conference or a release first. It was shown in a special video played on site immediately after the show on the 13th, and the agency's announcement followed the next day, today.

The people in the room knew first and everyone else knew a day later. Given that the fan meeting was called 'ON AIR', it makes a certain sense that the people watching the broadcast knew first.

They'll keep working through the end of the year, building toward next spring's album. The next marker is 26 October.
