hi and thanks for the replies. Ben got glowing reviews for his part
as Ariel in the Tempest. For example Kate Hoolu in occult e-books
says: The cast seem to be genuinely enjoying what they are doing,
perhaps a reflection of the age and experience mix- for some it's
their first time on stage, or they are still early in their careers,
for others it's `just another play' in terms of their CV's, but it
means far more than that to them, judging by their performances.
Prospero is played by the biggest `name' in the cast, Richard Briers
but it is perhaps Ben Silverstone as Ariel who steals the show -
every line is delivered with a wide-eyed effort, and he assumes the
role of an unearthly spirit to great effect.

Other critics, with typical British understatement, called
him "stunning" and "breathtaking". Here are some more accolades: As
Ariel, Ben Silverstone is engagingly eager to do his master's
bidding – a sprite with an ethereal voice able to summon a sense of
elemental magic. His winged arrival on one occasion provides powerful
visual theatre." (http://www.thestage.co.uk/paper/0242/0203.shtml)
All the best
