….the eight members of Kaspars Putnins's Latvian Radio Chamber Singers are given plenty of chances to display their stunningly pure vocal qualities as they drift round the stage like characters sleepwalking through their own fractured memories.

… the Latvian Radio Choir as perhaps the most versatile professional choral group in the world today. These singers not only deliver Dzenitis's fiendishly complex music with superb assurance and understanding, and entirely from memory, they also move and act with an intensity that would put many regular opera singers to shame. "You can ask this choir to try anything in workshop, and they never say no," Boyd says. "I'm not sure whether any professional British choir would have the same attitude."
