Anthony Roth Costanzo as Akhnaten, photo @ Karen Almond The Met company premiere of Philip Glass's Akhnaten is generally considered to the one of the Events of the Season (the other was Porgy and Bess ). Performances are sold out, the opening night got rave reviews , and so despite lingering pain from an ankle injury, I trudged to Lincoln Center. I had very high expectations. Akhnaten (1984) is the last opera of Philip Glass's "Portrait" trilogy. The others are Satyagraha (about Mahatma Gandhi) and Einstein on the Beach (about, well, Einstein). Akhnaten in the14th century B.C.E. upended the ancient Egyptian religious system for a monotheistic religion that focused on the sun-god "Aten." For the libretto of Akhnaten Glass drew upon primary sources from the Amarna period. He even insisted on presenting most of the opera in ancient Egyptian with no surtitles.
