"The Latvian Radio Choir was impressive as they offered a commanding interpretation of Brauns’ dissonant but not complex score. It was refreshing to hear the choir in this circumstance as they are so often occupied with the most difficult contemporary music in the repertoire. Klava allowed them to sing with power while maintaining balance and clarity."

"Viens gan ir skaidrs – Latvijas Radio kora jaunākā programma atkal palikusi atmiņā kā nopietns, muzikāli līdzsvarots un radoši piepildīts notikums, kas licis komponistu un atskaņotāju atklāsmēm sekot ar saspringtu uzmanību un kas kārtējo reizi saucams par jaundarbu autoru un interpretu oriģinālas un veiksmīgas sadarbības piemēru."

"The twelve men and twelve women of the ensemble, conducted by Sigvards Klava, sing together to form a superbly blended sound, with an excellent balance of voices."
