After teasing the collaboration online over the past few weeks, the Japanese and Spanish groups have unveiled their debut song together.
"UNITED GIRLS ROCK'N'ROLL CLUB" is, according to both bands, "a song that screams GIRL POWER!" They add, "You might be from different countries, different languages, but at the end of the day, the music speaks for itself. You can hear it, you can feel it! It's that type of song! Take a listen!"
