OMG, I had no idea you were linking to a Baby Metal video, you may have to change the title of the thread now to "Insanely Awesome **** frm the Internet"!
I am a HUGE fan, there is nothing else like them out there anywhere. Just a crazy mash-up of everything I love - brutal guitar-shredding metal, cosplay, etc. I've always been super into Jap rock like Melt Banana and Super Junky Munky and this bunch just takes it to the next level.
Cannot wait for the triumphant US tour!
