After Japan Nite, I have to give it up for Lolita no 18, ZUKUNASISTERS, Hystoic Vein, and Mo'some Tonebender.
There were others on the Japan Nite bill, but these are the ones I saw here in Seattle.
Lolita #18: straight up punk. Awesome fun
ZukunaSisters: rock with a soulful motown blend. ( I swear the Bassist looks like Miyabi from Berryz KOBO)
Hystoic Vein: Great rock sound, the girls really bring it.
Mo'some Tonebender: great rock, had a knack for turning noise into good music(and the lightsaber rave was cool too)
