One part of folk's remit is to honour the past and keep old songs alive; another to maintain the tradition of social commentary. This Hartlepool trio document Teesside history with gusto; this latest album has songs about the peasants' revolt of 1381, fallen second world war sailors and a potted history of the Middlesbrough iron industry. All are delivered in robust but precise three-part vocal harmony, often a cappella, with some accompaniment from guitar and squeeze-box. As bookends come pieces about a 2013 English Defence League "protest" at a York mosque being defused by tea and biscuits; like the album, a touching, singularly British affair.
