Most likely you haven't listened to these 3 Japanese girls touring with Battles right now, but they are one of the most impressive acts I have seen this year (judging by 10 mentions in the forum).
Their music is very repetitious, but it builds up and keeps progressing until it is totally rocking out. This statement leaves out the fact that they have one of the best female drummers I have ever seen. It is almost like she is from another planet, she is just incredible. I was more impressed by them then Battles who they opened for. They are a definite can't miss and worthy of checking out, but there is a huge difference watching their youtube videos and actually seeing them live. The girls seem very shy and coy, but are absolutely awesome when performing. The drummer is the main stage presence and is totally lethal.
With that said, here are a couple videos from the show. I didn't get any whole songs since they are really long.
Drum solo at the end of this song is insane.
