This is one of the best disc of Byrd's consort songs that I know. (The other is by Emma Kirkby and Fretwork, also highly recommended: Byrd - Consort Songs). This disc contains thirteen of his best consort songs from the celebratory "Rejoice unto the Lord" to the laments for Sidney (Come to me grief forever) and for Tallis (the sublime Ye sacred Muses), with love songs, lullabies and plenty else in between. It's an excellent, varied programme, full of Byrd's sense of melody and really inventive harmonic structures. Some people claim that William Byrd was the greatest ever English composer, and this disc makes that seem a defensible claim.
The performances are absolutely top-class. Robin Blaze is now regarded as one of the world's finest countertenors and this disc is a good example of why. His intonation is impeccable (not the case with every countertenor in the world) he has an unforced but powerful voice with a lovely tone and he sings the songs with real feeling for their meaning - Ye sacred Muses is truly affecting, for example. The viol consort Concordia have also developed an very well-deserved international reputation, and their playing here is delightful; immaculately controlled and balanced with a beautiful, rich tone and again with a wonderful sense of the song itself. They and Robin Blaze have a real empathy and the combination of their performances and the music produces something really special, I think.
In addition, the recorded sound by Hyperion is excellent and the notes are full and very interesting. It's a really excellent disc and extremely warmly recommended.
