The lead singer in this is Alba Armengou recorded last month, she's fourteen.
The other singers also all play instruments to a professional standard. From left to right; Andrea Motis, trumpet/soprano/alto sax,. Elia Bastida, violin, Rita Payes, trombone.
They grow up fast. Here's Alba soloing on trumpet in 2013 at the age off ten. I like the way students of the Sant Andreau Jazz Band in Barcelona are constantly being brought on.
It's embarrassing to say that we've no one in this country of this age with such a high standard of professionalism, but we have got "The Voice" and "X-Factor" and audiences who know no better, haven't we?
