By aged 43, I figured Daniel Harding would be at or near the top of the conducting heap—his reputation so well manicured (by a brilliant talent and very close associations with Rattle and Abbado), that a major post in Europe or the US would have been offered by now. A pleasant surprise was the music directorship of the Orchestre de Paris, the rough and tumble band that can, at times, be encouraged to provide top class music making. No happy ending, though. Harding decamped this year after only two years on the job citing, I think, artistic disagreements 'You are a supreme expression of a musical culture that is not mine.'. A nice way of saying I can’t be arsed to fix what's wrong [full statement here].
I've heard of other problems on podcasts of his working relations with US orchestras (LA and Chicago, specifically). Yet, through correspondence on social media, the excellent relations with many players of London Symphony as its Principal Guest Conductor, and from concerts I've attended, Harding seems to be a very charming guy as well as a superb musician.
