As Grammy-winning composer John Luther Adams puts it, his latest work An Atlas of Deep Time “...is grounded in my desire, amid the turbulence of human affairs, to hear the older, deeper resonances of the earth.” Commissioned and recorded with the South Dakota Symphony Orchestra under the baton of music director Delta David Gier, the piece taps into an ancient resonance that seems to hover imposingly, but benevolently, over our own existence – itself a blip in geological time.
