Green Day is one of those bands you never really hear about having side projects, but here's drummer Tre Cool doing exactly that in the goofiest way possible.
Cool's proclaimed "Icelandic death metal band" that is neither Icelandic or death metal is called Dead Mermaids, and whose brand new EP You're Welcome you can hear below.
I mean, look. It's clearly supposed to be pretty jokey and it's actually a lot of fun. It's crusty punk rock that Cool gets to play not Green Day-styled drums to, and you can play it for your friends and act like it's the greatest death metal you've ever heard. Though I think when they see song titles like "My Fish" and "Kill Eat Shit Repeat," they might be on to you.
