Hey past week I've been searching for something but haven't found it. It was an animated music video of 3 guys and it was kinda like a rock band ?? Idk but I remember the drummer had long hair and there was a weird machine they fought and lava everywhere and in the end it changed to the actual people getting ready for a performance. Does that ring a bell to you? It was really popular cuz the animation was fantastic but I still can't find it
That was Freak of the Week!
Traditionally animated by Juanjo Guarnido and a team of animators. You can read about it at Cartoon Brew and also check out the making of video:
