How Concert LED Wristbands Work | WSJ Tech Behind

[@scferro]

The IR virtual “spotlights” are such a clever idea!! I love seeing old school tech repurposed in cool new ways.

[@Songs-lr4wt]

Even in Celine Dion tour in 2019-20, they used drones that changes colours and moves extensively.

[@bwoogie]

as soon as i heard that they used IR i thought it was such a bad idea... IR requires you to be in line of sight for it to work. Then I saw them mask the signal with a gobo to make shapes i thought it was such a brilliant idea. They literally took a disadvantage of the technology and made it into an advantage.

[@karthikramprakash]

Last year I went to a Coldplay concert in Frankfurt and I got to experience this awesome light wrist band. It really makes you feel like you’re an important part of the whole show and exponentially increases your excitement and adrenaline rush.

[@winterbelle03]

ive been to a few kpop concerts and wondered how this works. i think its really cool and for kpop, i like how to get to keep a piece of the concert and a symbol of the group even after its all over. i hope the wristbands used in most events are being sanitized and reused. i think the lightshow is so cool because you get the best view of it up in the nosebleeds, so it makes even the "worst" seats worth it.

[@LLUEVE]

Coldplay owns this tech. A father and son proposed this tech in 2012 to the band for the Mylo Xyloto tour. The bought it and then licensed it out. (XyloBands) The father and son get $1 for every ticket sold at all these concerts. It’s a pretty awesome sight to see! (It’s also how Top Golf tracks your ball)

[@sidoitsu8179]

As a J-Pop fan especially a Hinatazaka46 fan I do have my doubts about these controlled light sticks, they might be usefull at concerts with a lot casual fans, who do not know the fan choreographies by heart, to give them a memorable concert. But for hardcore fans light sticks are a way to communicate with the members on stage by creating their own fans choreographies. E.g. when Hinatazaka46 got their song Joyfull Love the group also got a commercial campaign were each member had to wear a dress in a different colour and in the video they had to form a line and it looks like a rainbow. The first time the group performed this song at a concert the fans dyed the arena in rainbow colours and all members felt the love of the fandom. Since then the song is performed at all concerts and the fans take pride to prepare for the moment the song is announced.

[@kodakkevin]

I'm such a fan of artists and engineers pushing the envelope with old tech. Kind of similar to how Christopher Nolan keeps proving how far the film format can be taken, I feel like people move onto new tech too fast and we rarely achieve the fullest potential of older more accessible tech that hasn't been mastered yet!

Lightsticks definitely i feel are the top at this game when it comes to it. Its not a one-time thing, its customizable, and the use of bluetooth definitely makes for a better experience. its definitely a fan FAN thing though, and i think just a kpop thing too.

[@jas_bataille]

Not sure how Bluetooth makes it for a better experience. I don't want to have to fiddle with an app for my expensive souvenir to work, and I certainly don't want it connected to thousands of other phones inter-connected into one giant hub. I don't know what kind of thing they can scan once you give them permission. Whereas the wrist band is 100% fool proof, free, doesn't distract from the concert, 100% private... I'd say for the intended purpose, I'd take the wristband any day.

​@@jas_batailleyou aren't connected to thousands of phones, you're just receiving the Bluetooth signal. And from what they are showing, the light show is much more detailed and it sounds like they are reusable rather than used once and toss in the trash.

[@maplenerd22]

[@brownpaperbag6159]

@@jas_bataille Recently the tech has been updated to automatically connect your lightstick to the venue's controllers, a good example is BTS. Before you had to either connect the light to your phone, or via a venue booth. Now just turning your light to bluetooth mode will automatically connect it to the controller. So now it'll work similarly to the light bands that performers and festivals use.

Good explanation of an admittedly interesting application of technology. Though, one wonders about the amount of un-recycled e-waste generated and the amount of lithium thrown into landfills.

You can even see the non-releasable polyester cinch wristbands in the animations, implying that returning at the venue is very unlikely.

This is actually entirely Coldplay's tech, at least as far as music touring goes. They bought up the idea from a guy called Jason back prior to the Mylo Xyloto tour (hence Xylobands) and have been using it ever since. Generally they now license it out for other people to use at their own concerts too, but I still remember those early days where Coldplay were the only ones who could do this.

[@LuizHartkopf]

nope, Coldplay might've been the first ones to use it in the USA. other's have used this in Korea/china waaaaay before that, even in the 90s

[@Robo94100]

@@LuizHartkopf I’m not sure what technology they were using in the 90’s, but I’m referring to the specific technologies that Coldplay now has the patents for, and allowed the technology to be used in even more innovative ways than similar examples previously. Also I feel it necessary as a Brit to point out Coldplay aren’t from the US haha 🇬🇧

[@ORGGStudios]

I was a bit sad that Coldplay wasn't mentioned at the start and only as an example at the mid/end of the video. When Coldplay had the xylobands for the first time everyone was speaking about it. It was so unique and new. Adds such an amazing new layer to the light design of the show

[@jas_bataille]

Well... if that's "entirely Coldplay's tech" and if Coldplay own Xyloband and has patented their technology... then it *can't* be entirely Coldplay's tech now, can it? I get the point you're trying to make, which is to point out who the "inventors" where but... I mean they're not going to sell their patents to someone else (at least I don't think so). Montreal is the city with the most festivals in the world and we are known worldwide for being top providers of anything you want in the event industry with several companies ranking very very high (Solotech being 3rd biggest event tech company in the world). What I mean is, I would be more than surprised, since Xylobadn is still very much in activity, that Pixmob is based on their patents. They (or more likely someone on their team with the name of the band being incorporated so the patent belongs to "Coldplay") wouldn't sell that tech, and no Montreal start-up would have the capital to get a patent like that. Nope, they figured that one out on their own, and it's different enough that it doesn't infringe the patent. So, not entirely Coldplay tech... I mean I really don't think so.
