Four instruments that should not belong together, and four hundred years that vanish when they play: the Vervain Consort make the border between court and street sound like the invention it always was. The evening's conceit — a masque tune followed by the ballad that stole it, the ballad followed by the divisions that dressed it back up for the parlour — could be a lecture, and in other hands has been. Here it is a band showing you their favourite tunes from four angles.
The sound is the thing. Mensah's gamba and Iyer's theorbo make the courtly floor; then Whitlock's hurdy-gurdy arrives like weather, and Bankole's sackbut sings over the top with a directness no cornett could manage. When all four finally land on the same ground bass, the room leans in.
By the encore — a Playford set taken at true dancing speed, which is faster than concert speed and everyone knows it — the audience was stamping the floor of a Grade I listed hall. Nobody stopped them. That is the point of this group.
