Atlanta Symphony Chorus, Atlanta Symphony Orchestra, Robert Shaw - Philip Glass - Itaipu / The Canyon (1993)

Itaipu (1989) is something of a cantata-cum-symphony-cum-oratorio with no clear text. Its topic is the world's largest hydroelectric dam, built on the Rarana River between Paraguay and Brazil, and the piece--in Glass's trademark punctuating minimalism--is filled with distinct South American instrumentation, particularly in the percussion. The music itself is noble, conjuring the human endeavor to build the five-mile-wide dam near the town of Itaipu. The Canyon (1988) is about no canyon in particular but tonally suggests the mystery of canyons in general. Both these compositions are among Glass's better works. -- Paul Cook
