Too fast - I wish they'd had more of the music on its own, but it was mostly talking. (Frankly, I would have liked the interviews and music, and not as much narration.)

The Rankin Family, the Chieftans, Mary Jane Lammond, Capercaille, Maire Brennan, Altan, John Allan Cameron, Lorena McKennit, Ashley MacIsaac, Natalie MacMaster, Dougie McClean, Seamus Eagan, Mary Black...too many people to comfortably fit in one hour. (Sorry for any misspellings.)
