"I have never heard of Jarlath Henderson - so I listened on YouTube......good voice and what he seems to be doing is an extension in the process of taking Traditional songs and giving them a modern treatment"

I've not heard of him either,
so I just did a quick youtube of the intros of three of his performances..

errrrrmmm.. what's modern about a bloke singing folkie songs over a pipes drone or acoustic guitar...

What am I missing...???
