Songs for Humanity: A Celebration of Ten Years, 1988-1998 is a documentation of the brilliant cross-cultural ambience of Peter Kater and R. Carlos Nakai. The collection spans ten years, six CDs, and 13 compositions, two of which are new. Nakai and Kater blend acoustic, symphonic, and electronic elements with style, grace, and class. Kater's acoustic piano has vibrant timbres. Nakai's flutes are strong and atmospheric. The soundscapes have immense depth. This essential collection will appeal to fans of Douglas Spotted Eagle, Robert Tree Cody, and Little Wolf Band. ~ Jim Brenholts, All Music Guide
