True, I do see a thriving ecosystem here in Europe for some more fringey types of acts. There's like resident advisor ( https://ra.co ), XCEED ( https://xceed.me ) . Probably because some events don't meet ticketmaster's T&Cs (they can be a bit spicy).

In fact I have not used ticketmaster in the last 2 years, the last time was a big ticket stadium-type thing. Most of the events I attend are doing it through resident advisor and I have about 40 tickets in my history there now. I'm glad the ecosystem hold by ticketmaster is being broken, at least here in Europe.

Though even there you do see some ticketmaster crap popping up like universe.com
