Ethan Iverson & Ron Carter

The Bad Plus pianist knows the value of living history – he’s made a point of interacting with elders during the last few years, and to a one, come away with intriguing results. At 41 Iverson is about the half the age of his partner, a revered bass master who has become one of improvisation’s icons after a lifetime of extraordinary work. Their book of duets will stress standards, and the give ‘n’ take in such a cozy room – designed specifically for this kind of intimacy – will explode the goose pimple factor.
