DANIEL LENTZ: “O-Ke-Wa,” “Missa Umbrarum,” “Postludium,” “Lascaux.” Lentz Ensemble. New Albion Records NA 006. These Lentz classics for chorus and wine glasses, or Amerindian-type percussion in the case of “O-Ke-Wa,” have held their inventive edge, remaining vivid, entrancing sound scapes--and occasionally exasperating, as in the sustained whine at the end of the Mass Kyrie. The performances and the recording of this disc present well-meshed yet fully articulate textures, more insinuative than insistent but quietly urgent.
