Why are these concerts/shows $100 now?

I get that it takes a lot of effort to create and organize these things….but isn’t it kind of excessive ?

I remember buying MauP tickets for $40-$50 a few years ago for a show at a big concert venue… now I’m looking at the HARD afterparty website it’s $110.

Looks like I’m sticking to undergrounds… but it would be nice to attend a mainstream event here and there hang with friends who aren’t into the underground scene.
