If anyone is interested in more traditional Japanese music fused with "modern rock" than you should check out this band.. quite an interesting blend of Okinawan, folk, and rock.. Donal Lunny, who is married to one of the founders, plays along with them at times.. as does Andy Irvine on the second lp..
