Nobody expects a Japanese koto to sit inside a funk groove and sound like it was always meant to be there -- but that has been Hiroshima's whole quiet miracle for almost fifty years. The band took the thirteen-string koto, wrapped it in jazz-fusion horns and a soul backbeat, and earned a Grammy nomination bridging two worlds that were not supposed to meet. Live, it is hypnotic; you go in curious and leave a convert. South Coast puts them on the lawn on an August night in Temecula wine country, the kind of setting that suits music this warm and this strange. Come for the novelty of it and stay because the groove will not let you go. Go in convinced you have heard it all. You have not heard this.
