As I have said, I have never seen the ad. but as for Paul Mounsey, I have his first three CD's Nahoo 1, 2 and 3.
He is one of the most exciting things to come out of Scotland in a long time.
His first album was mostly sampling odd bits of gaelic and maybe a bit of Runrig with a lot of musical input by himself. Now an old traditionalist like myself took quite a wee time getting used to this but his work is a superb art form and by his third album, I love everthing that he does. (I suppose it's like what it was when sythesizers were first used by folk bands).
Paul lived in the Easter Ross-Shire town of Alness and now lives somewhere in South America and aparantly is big in film music.
I can only recommend that you try and get a listen to his stuff.The "Don Roberto" track on Nahoo 3 stands out as a personal favourite.
