Andy Irvine and Paul Brady startled and stilled the folk world 35 years ago with their eponymous album. It was a graceful, low-key affair, but one that came bubble-wrapped in Irvine’s calculus-like rhythms and melodies, and both singers’ Arcadian vocals. Brady’s reading of

Arthur McBride

has never been matched, while

Lough Erne Shore

and

Bonny Woodhall

stretched and bent Irvine and Brady’s musicianship in shapes that few would seek to emulate.

The duo first revisited the album a few years ago at Glasgow’s Celtic Connections. Chances are they have unpicked further the knottiness in the arrangements in anticipation of this weekend’s reunion.
