A first piece, "In Air Clear and Unseen" is played he Keller Quartett and Oleg Malov (piano).
Then, the Russian soprano Tatiana Melentieva sings "the Song of the Most Holy Theotokos" (Svete Tikhiy) and her voice is treated by a digital sampler (Andrei Siegle) in order to create beautiful choral patterns.
This beautiful album is a masterpiece, and it is very difficult to compare it with anything else.
One could say, as a rough definition, that it might be located at the crossroad of Brian Eno and Arvo Pärt...
