Vivivi

The ever-shrinking hinterland between idol pop and the indie scene continues to spawn fascinating mutations. This all-nighter offers a mélange of chiptune, anime songs and straightforward girl-group pop antics, with live acts including Band Ja Nai Mon! (a singer drummer duo featuring Shinsei Kamattechan's Misako), YMCK and BiS. There's also a bulging roster of DJs, among them Block.fm's El Poco Maro, DJ Nemukyan (aka Dempagumi Inc. member Nemu) and circuit bender Julie Watai.
