To the crowds of non-Kpop fans that will be there who are the target audience, Aespa is just as nugu. Taemin is at least a better performer with music that is actually marketable there. At this point, it seems like SM is just using Coachella to media play and earn clout cause they saw how well it played out for Blackpink. It's the same kind of noise marketing they used with SuperM to make it seem like they were larger than life in the West when they weren't.
The point is this kind of senseless using connections to get gigs might make for a great headline, but not much else. You have to actually have substance to back it up for it to really have an impact. Then again, who knows. Maybe SM will have a great team behind them to give better remixes of their songs and the girls might have improved their performance skills and sing live.
But as of right now, I'm skeptical af.
Aespa making more noise internationally than Taemin and that's what the promoter looking for. Honestly after RV and Exo , aespa is better bet.
While this is huge risk kinda like Mama Bird pushing baby Bird from 10.000 ft but SM knows no matter the outcome of this event, aespa popularity will growing significantly after Coachella just like how SuperM helping the members each respectives groups sales and popularity, I think SM wants to target that first.
