It's a good thing about the Wikipedia article, because now I know what the heck ya'll are talking about.

"Transatlantic Sessions is the collective title for a series of musical productions by Glasgow-based Pelicula Films Ltd, funded by- and produced for BBC Scotland,[1] BBC Four[2] and RTE of Ireland.[3]

The productions comprise collaborative live performances by various leading folk and country musicians from both sides of the North Atlantic, playing music from Scotland, Ireland, England and North America, who congregate under the musical direction of Aly Bain and Jerry Douglas to record and film a set of half-hour TV episodes...

In addition to the TV productions, public performances of the Transatlantic Sessions have been staged recently... and five series albums have been released in both CD and DVD format..."

I'm glad to hear of it, although I'm not in a position to view it myself.
