Salvatore Martirano's hallucinatory anti-war piece L's GA, in which a narrator recites the Gettysburg Address while inhaling nitrous oxide, was given a potent revival tonight at an LA Phil Green Umbrella concert, with the performance artist Ron Athey in the gas-mask role. (Electronic modification was used in lieu of nitrous oxide.) The program, under the direction of John Adams, also included Anna Thorvaldsdottir's AURA, Andrew McIntosh's luminous new brass-ensemble piece Shasta, and Julius Eastman's Evil Nigger.
