See the link in which you can watch or listen to the first of the five lectures. It's just over 1 hour long but worth watching if you are interested in Barenboim's views.
Interesting indeed - and it's "Reith", incidentally, as in the link itself (sorry to sound pedantic, but...). Perhaps people might like to contribute their thoughts on it here...
Best,
