Music must have spirit and soul - this basic attitude of jazz, its search for the unheard, for the power of emotion, its unrivalled inner and outer freedom, that is the inspiration of ACT. "In the Spirit of Jazz" follows this leitmotif - with Youn Sun Nah, Nils Landgren, Viktoria Tolstoy, Leszek Mozdzer and Wolfgang Haffner, among others.
