Most people at Coachella are there to get high and party and could give a shit about who is actually performing, especially if it's not a headliner or sub-headliner. 88rising so by extension CL/2NE1 also performed on the main stage with no impact amongst anyone who was not already a KPOP stan
Coachella did not even matter for Blackpink, really. At the point BP performed at Coachella, they were already charting regularly in the US and Coachella was the launch point for their US tour. Their first show was The Forum the very next week. Did performing at Coachella help their career in the west because everyone at their set magically became a fan? Lol no. I think Coachella really helped them mostly because their performance blew up on social media and gained a large virtual audience. But BP already had the momentum and would have continued to chart in the US with or without Coachella.
SM does not understand this. I think they see Coachella as a massive stepping stone, otherwise they would not have Aespa making this huge leap from pre-recorded Korean awards shows to 100% live American music festival. Also, the fact that they are debuting a new song when they easily could just performed a b-side? Half the fun in Coachella is stoned influencers singing along to songs they can actually recognize...debuting a new song which no one will know the words too is an interesting choice but probably an SM tactic to get more people to tune in
In any case, as an objective non-hater and a non-delusional stan, I think SM is going about this weirdly. Also the headlines are a LAUGH and part of the reason they are being dragged. Good luck to Aespa!
