The voice (from Lincolnshire) is small, wispy and often "pitchy".
The accompaniments are equally small, quiet and sometimes pitched to sound like the creaks and gurgles in the staves of a house. The songs are traditional and obscure. What you get from this will depend on your receptiveness to the creaks and gurgles of feeling that the music stimulates in your breast. Alasdair Roberts is on it, a clue to the levels of starkness and ghostliness to be encountered within. Rather good.
