Ceol's Craic, a Glasgow-based club devoted to promoting Gaelic arts, brought Mairi & Alasdair together to make Urstan, which takes it's title from a Lewis-specific word for a celebration held at the birth of a new child. Most of the tracks are traditional Gaelic songs, with a few Scots songs & self-written tracks too, all played in new, forward-facing arrangements by an ensemble including guest appearances from such Glasgow music scene luminaries as Michael John McCarthy, David McGuinness, Ross MacRae, Richard Merchant, Peter Nicholson, Mike Gastings and Gaelic song authority Allan MacDonald.
