Ex-Girl is an all-girl Japanese music trio who plays a great mixture of Casio-techno-pop-o-punk and sings in different vocal styles (from shrieking punk diva banshee to cute girl to almost operatic vocals) with strange harmonies.  This wacky female trio from Tokyo sings like Andy Warhol paints and delivers it on stage like cartoons.  The result is an inspired mix of musical invention and pop playfulness that's like nothing else you'll see this week.  Sunday, April 16, 9 p.m., $6, The Clipper, 402 E. Fourth Ave., downtown Olympia, (360) 943-6300. - Brad Allen
