Personally I quite like the "treatments" he gives to the songs but cannot get on at all with his voice which drives me up the wall.

Nor do I think the music press (and folk music pundits in particular) do him any favours with the hype they broadcast. What he is doing is not new or particularly innovative - even in folk circles. I doubt that he will have any influence at all in bringing non-folkies into the fold despite his youth and electronic wizardry but good luck to him anyway.
