If you're in Australia, then consider supporting the best Irish band in Australia - any CD by "Trouble In The Kitchen" from Melbourne. Some very good songs on their recordings as well as superb flute and fiddle playing.
On the other hand, if he's just 12, a purely fiddle album might be a bit "hard core". A band might be better - my favourite Irish group currently still performing is "Teada". Check them out.
All of the fiddle players mentioned above, are of course, excellent.
