The brief opening piece for chorus on this new release, "Da Pacem Domine," is based on a 9th century Gregorian work and has the usual, familiar--and very beautiful--Pärt-ian characteristics: a soft, endless stream of easy tritones and harmonies that make this plea for peace immensely moving. The major work, Lamentate, is scored for large orchestra and solo piano--a very unusual combination for Pärt. Even his fans will be surprised. In ten brief sections, it begins with a quiet drum roll, immediately followed by horn calls. There are forte explosions for full orchestra and piano, with heavy percussion. At times the only thing we hear is a hushed piano part with strings supporting very quietly. The effect is dark yet alluring. It ends peacefully. This is another stunning CD of Pärt's music for his fans--old and new. --Robert Levine
