In 1982, Leonard Bernstein visited London and gave a concert at the Royal Festival Hall which featured Elgar's "Enigma Variations." It is now known that he and the BBC Symphony Orchestra didn't exactly hit it off, while his reading of Elgar's work proved to be somewhat controversial. As an example, here is the "Nimrod" variation performed in what is believed to be its longest duration. The whole concert and the first rehearsal was issued by 'ICA Classics' on DVD (Catalogue No. ICAD 5098) from which this extract is taken.
