The hour-long Two Gongs fills the entirety of [this] disc with its ethereal, droning psychedelia. While written in 1971, the '89 recording documented here features Chatham, along with fellow composer Yoshimase Wada coaxing heavy, overlapping tones out of a pair of Chinese gongs. The instruments buzz and hum, moving in waves from deafening rattles to soft, muted drones. The monstrous noise that Chatham concocts is far more akin to the seismic crashes of monstrously distorted guitar feedback than that of two unprocessed slabs of metal, and it proves the composer's interest in creating a similar world of sound out of whatever instrument currently proved his muse. On disc, the performance is jaw-droppingly powerful, a monumental chunk of glorious noise.
