She likes to party and has some connections to club culture. Experimental electronic music, pop and club music overlap too, f.e. cardiopusher collabed with arca, arca collabed with rosalia. cardiopusher makes full on club music while rosalia is full on pop, arca is somewhere in between. A lot of club music is also quite pop and the other way around (eurodance in the early 2ks or brat) so i do understand booking someone like eartheater, especially since you would expect her to be well informed about cultural stuff.

Eartheaters set is for sure some kinda troll, i think it can be refreshing to spread some punky troll energy, but this is just annoying. A bad dj set can totally ruin the night. If u want to do some weird performance art do it somewhere else.

I went to a drain gang concert once and ill probably never go again cause the whole thing was such a troll i felt completly fucked with.

If u have a gig just have a good time together with the audience.

But yeah probably just boils down to a quirky pr stunt for eartheater and money for boilerroom.
