AT THE age of only 45, Kate Rusby has already attained national treasure status, certainly in the English folk world but possibly even beyond that.

Yet there’s no sign that she’s resting on her laurels. On this third date of an intermittent spring tour, she provides ample proof not only that her songwriting skills are as sharp as ever but that the inspiration continues to flow.

Mainly, that evidence comes in the shape of some fine compositions from her forthcoming album Philosophers, Poets and Kings, due out next month. But it also shines through in a performance that demonstrates how much joy she still derives from songs and singing.
