They’re not bad. Kinda reminds me of Blink 182, The Mothers of Invention, Rage Against the Machine, the Red Hot Chili Peppers, et al.
The english subtitles are NSFW
Aye, they used to be great. Nowadays they’re just another pop band, although less electronica-y and more pop/rock-ish. Back when they first showed up, tho, they sounded awesome: Houchou Hasami Cutter Knife Dosu Kiri (Long ago someone posted the original video for this song, and the band is fun to watch, but the audio quality was terrible, so I linked to this other one).
