Powaqqatsi: Life in Transformation is 23 years old, but its message — about the dubious effects of industrialization on the ancient traditions of the Third World — is as relevant as ever. That's because when you come right down to it, human beings don't really change, and history never fails to be ignored and, therefore, repeated. The brilliant sequel to Godfrey Reggio's 1982 experimental documentary Koyaanisqatsi: Life Out of Balance is so inexorably linked with its score that the work contains the unique billing, “A film by Godfrey Reggio and Philip Glass.” Indeed, you can't think of either Koyaanisqatsi, Powaqqatsi or the final film in the “Qatsi” trilogy, Naqoyqatsi, without hearing Glass's intensely evocative music, which uses native, classical and electronic instruments as well as themes to take the entire experience into luminous realms of emotion, mysticism and even, perhaps, epiphany. This week, revisit Powaqqatsi in all its visual and aural glory at a screening at the Bowl featuring live accompaniment by the composer and his Philip Glass Ensemble, with the new addition of the voices of the Los Angeles Children's Chorus. Michael Riesman conducts the L.A. Philharmonic.
