Charles de Ledesma reviews a new CD collaboration by a celebrated Japanese folk singer and an expert Hawaiian slide guitarist. It's called Nankuru Naisa. Takashi Hirayasu and Bob Brozman collaborated on last year's CD Jin Jin, which was a surprise success. While they weren't on tour across the world, they recorded some more of their particular brand of guitar and folk music, which are now on their new CD. (4:00) Nankuru Naisa is on the Real Music Network label.
