What a difference a change of scene makes. During Sakari Oramo’s 10 years at the helm of the City of Birmingham Symphony Orchestra he wasn’t exactly diffident; but you felt you could invite him to tea without any crockery getting broken. Now, I’m not so sure. Last night at the Proms, conducting one of his three current babies, the Royal Stockholm Philharmonic Orchestra, his arms spun like windmills. His torso lunged to the left, then to the right. With energetic facial expressions he made love, picked a fight, grinned like a clown - whatever was needed to propel the emotional dramas of his all-Scandinavian programme. And the orchestra seemed wired to his every move. I’ve never heard such an exciting or compelling performance of Nielsen’s Symphony No 4, The Inextinguishable – the symphony with the duelling timpani, and certainly inextinguishable on Monday night.
