Help me understand- Angine de Poitrine

I was told about this band today and a coworker showed me a youtube video of what they’re like.
My question is not a joke, but the existence of this band may be?
Help me understand? Wtf this is? Is this an attempt to troll the world that people have accepted as “rock music” so they kept going? Is this “real music” and I’m the idiot?

It feels like elevator music for people in the “Beavis and Butthead” universe.

WTF IS HAPPENING?! (And no I’m not just talking about their absolutely ludicrous appearance, I’m talking about the whole package. The music sounds like LSD fueled song intros looped together without ever reaching a chorus, ever.
