Kingdom Legendary Wars: Episode 4 (part 2 of 3) The Boyz

they have no making vids bcs some groups depended on their company and staffs but group like ateez got involved a lot in the making

Not sure who does the high note (I don't know The Boyz that well), but you can see him doing it live. He's standing in the back on the right side while everyone else is dancing. I think the camera didn't focus on him because it was the "grand finale" of the song with a lot of explosive group choreo, so to focus on one person would've taken away from the performance's (visual) impact. I totally get it's a bit of a let down when you're mostly here for the vocals, but the choice makes sense for the overall performance imo. It's pretty common for kpop performances to have an explosive end of the song where you have one guy popping off vocally just standing there while the rest dances (I think it's kind of a kpop thing lol). In such instances the camera usually focuses on the whole group and not just the member singing. Ateez highlighted Jongho's voice in their previous performance by creating a solo moment for it & not doing it during the ending dance break.

The guy from SF9 with the low speaking voice is Zuho!

The high vocals were started by New (Chanhee) then later on some support notes were done by sangyeon and jacob! But the loud high note was New and it was totally live. You can see him standing on the right side

TIM, I know this group like I know the members of my family. The notes are definitely New, and they are live. New is the only one in this group besides Sangyeon that can reach those notes and that wasn't Sagyeon's voice so that was definitely New. You can see him in the back on the right side while everyone is dancing. About at 1:05:30 in the time of the video you were watching, the episode. Also, I would have loved that just like the others, you watched the entire version of SF9's original video of "O Sole Mio". Also, about tight group dancing, I think TRCNG is probably the tightest in the industry with males, followed by Seventeen probably. Just to satisfy my fangirl heart in a pause you could maybe check a bit of https://www.youtube.com/watch?v=XsSZ_VA_Luo OR https://www.youtube.com/watch?v=sZZriji92Jo (These are two choreo videos from TRCNG, don't worry you probably won't get requests for them cause they are disbanded).

i *believe* the high note is New! it sounds like his voice and he’s often one delivering very impressive high notes!

I'm not a The Boyz fan, necessarily (the only group from this show I follow closely are Stray Kids), but they have some very cool performances. Correct me if I'm wrong, but I believe the one singing those crazy high notes is New - you'll hear more from him in some later episodes. He's got a killer voice for sure. Also I think their fandom is called Deobi (pronounced kind of like "The B"). Their choreo synchronization is always on point. Also - the intro to this performance reminded me of something. If you ever want another musical/movie to watch, check out Baz Luhrmann's Moulin Rouge! The Tango de Roxanne from that movie rewrote my DNA a little lol. It's a very cool jukebox musical.

i’m a fan of the boyz, aka i’m a deobi (generally pronounced ‘the-b’ with a harder TH sound closer to D) and admittedly while i don’t know them super super well, i think their performances on Road To Kingdom would be an incredible dive to see them more! some of the most impressive performers in all of kpop in my opinion, and road to kingdom especially shows that

There are a select few performances that I really love from Kingdom and this is easily one of them. I love the concept and their cover of sf9 is well done. The Boyz are honestly such underrated performers. Their dancing is incredibly tight and their vocals are easily some of the best in kpop. It's a shame they've had such poor luck with companies over the years.
