This is one of my favorite fake bands.
Not a band. It's the band in a movie. It's actors playing - check Bae Doona on vocals, and Girls #15 Aki Maeda on drums - but it's really good.
In this case it's Paranmaum ("Blue Hearts" in Korean, I'm told) covering The Blue Hearts "Linda Linda." It's from the movie Linda Linda Linda, which is extremely watchable. I could follow along even when I caught about 10% of the Japanese. And it has a dream sequence featuring The Ramones.
If you keep going they go into Owaranai Uta over the credits. Yeah, you just caught the payoff. Still worth watching the whole movie.
