Rich, very evocative collection of exciting music from Brazil: in the group's hands the music becomes a vehicle for issues like ecology; the South African struggle for freedom; the beauty and wonder of the earth's resources, like water; and the dilemma of who the earth should serve: future generations, as the earth-savers would remind us, or the hungry mouths of the present, as the cattle-raisers and the clearers of the land would have it. An important time capsule of present-day concerns. On the artistic side, the consistent excellence of the quartet is graced by the vocals of Jhabvan and the work of Brazil's finest new composers like Ivan Lins and others.
