American Routes, the public radio program produced at Tulane University, is leading a tour of American “roots” music to China, April 30 to May 3. (...) This concert series builds on our prior China tours with Cajun music, gospel, cowboys and jazz. This kind of vernacular cultural diplomacy is both entertaining and edifying. The virtuosity and diversity we bring to ‘Meet-in-Beijing’ is a great statement between nations at an intimate level.
