	At Times of Quiet	箏 : 栗林 秀明 尺八 : 田辺 頌山
Written for shakuhachi and jushichigen (17 stringed bass koto), this piece was a commission for Hideaki Kuribayashi's 1989 Tokyo recital at Vario Hall. In composing the work, utilization of the bass koto's rich and deep reverberating tones was utmost in the composers mind. The piece was retitled "SO" at the time of this recording.
