And this, sung in ancient alie...I mean, ancient Egyptian.
Philip Glass Akhnaten (singing archaeology)
'Akhnaten' is part of a sonata trilogy by Glass in his minimalistic style, the others are 'Einstein On the Beach' and 'Satyagraha'.
Such perfection in these voices makes even a bird envious, or in this case, a Birdy quite breathless. Incredible ranges. Makes violins weep.
