It’s Batman meets Metal.
In particular, this is ArhyBES’s take of Dethklok’s Face Fisted. Their “new” band is called Children of Batman and this remake is called Batface.
You might not want to listen to this at work because, well, metal. And swearing.
I like the arrangement of Red Hood, Robin and then Nightwing across the stage; with Red Hood and Nightwing on guitar. No spoilers as to why if you don’t know those characters but I imagine you can work it out.
