Kodo’s new album, “Mondo Head” (on the Sony Classical label), produced by the former Grateful Dead drummer and world music enthusiast Mickey Hart, the Sado Islanders are showcasing their old-school taiko chops on the One Earth Tour. If you want to see Kodo in their pure, unadulterated element, this is a good chance.But if you want a taste of traditional taiko turned on its head, check out “Mondo Head.” Nominally, it’s a Kodo album, but in reality Hart’s vision drives the project — the latest with his Planet Drum retinue of global drummers, vocalists and guest artists. It’s a one-take affair that Hart described during a July visit to Tokyo as “Kodo drumming with other elements of the world to form yet a new kind of taiko; it honors the old tradition but this is how music grows and progresses.”
