In Amadis of Gaul, a 15th Century Spanish myth, war erupts after Oriana, the daughter of the King of Britain, rejects marriage to the Emperor of Rome. The King's Singers deliver these songs with insistent voices, the imitative pairs beautifully balanced across the stereo, the intonation faultless and the diction unmistakable. The variety of tone that the sextet achieves is one of their inimitable traits. Hear how they darken in the second half of Wilbye's The Lady Oriana. Other groups can only admire.
