Japanese pop-music girl group plays klezmer-inspired music

Susan Delson of the Wall Street Journal profiles the Japanese sister duo Charan-Po-Rantan, featuring accordion music that "glides from klezmer to Balkan beat to zydeco, from French chanson to blues and boogie."

The music of Charan-Po-Rantan is rooted in the accordion, not a common instrument in Japan. But it was the one that Koharu set her sights on when, at age 7, she attended a performance of Cirque du Soleil.

"I told my mom, I want that thing that stretches in and out," Koharu recalled.
