Who Is The Next Big Rock Stadium Band/Tour?

I have a question and it’s genuine. I’ve not been to a concert in almost 20 years. Are they generally still a big deal?
I’m asking because my kids, 18 and 20, respectively, have never asked to go to a concert, and I know they listen to some of the more popular artists. My wife and I even offered to buy them tickets and they declined each time. Their friends are the same.
I guess I have two questions. Is there an abundance of good, new music out there?
My students are still gaga for Taylor, but she’s the only concert I hear them talking about
Maybe one student was excited about an Olivia Rodriguez concert (maybe in Houston)
BUT
Lots of older kids still do festivals- I know a few of my kids were going to big festivals this summer
