Wow! I had NO idea the girls of Perfume could actually sing... I always hoped they could, but this only makes them cooler. A-chan is REALLY good, seriously, and Nocchi surprised me too. Kashiyuka not that much, but passable. I am also really pleased their singing voiced aren't as nasal and extremely high-pitched as girl group vocalists' tend to be!
I would kind of like some kind of Perfume Acoustic (or at least non-autotuned) self-cover album, haha. Like the Laserbeam cover posted earlier, but then sung by themselves and perhaps just as energetic as the original songs, only no to little electronics. That would rock my world.
Alternatively, just a few songs on the new album with fewer auto-tune. Or an alternative version. Just SOMETHING.
