We’re talking in Berlin for two reasons: Andrew Litton has just renewed his contract with the Bergen Philharmonic – he’ll see out at least 12 years as the Norwegian orchestra’s principal conductor – and they’ve now reached the holiest of holies on their European tour, the Philharmonie. The long-term relationship is rare enough, given the musical chairs of today’s higher-paid international conductors, though not unique. Yet it seems to me that what they have together probably is - and I can say, hand on heart, that the Bergen/Litton Berlin concert knocked spots off the one time I heard the Berlin Philharmoniker and Rattle play in their fabulous home.
