Japanese group Babymetal mix metal riffs with pop choruses and choreographed dance routines.
A Japanese girl group that mixes heavy metal riffage with pop choruses has confused the heck out of Americans with their US television debut.
Babymetal, who have racked up millions of views on YouTube with the frenetic genre-mashing of songs like Karate and Megastune, made their US debut on
The Late Show with Stephen Colbert overnight.
The three teens performed their biggest hit Gimme Chocolate!! complete with a band dressed as ghosts and ghouls while performing choreographed dance routines.
Colbert warned viewers beforehand: "I'm not sure what I'm about to see. But I'm pretty excited about it!"
