What is this bass music group called?

So a while ago I saw a Youtube video of a group of three bass players playing a concert. I do not mean bass guitar, I mean the giant upright bigger cellos.

They had a rock/metal sound and the one video I saw was a remix of some very popular older song(which I can't remember right now.

I know one of the bassists has long blond hair and they were all guys who were shirtless.
