Mehta is ageing in fine style: the control and precision of his conducting remain phenomenal, yet there is none of the sports car gear-changing which, in earlier vintages, he often seemed unable to resist…The encore, the Swan Lake waltz, is so excitingly played that if you were dancing to this, you’d surely end up airborne.

There’s a palpable sense of occasion…Mehta is an old-school conductor and the playing here has plenty of the grand manner about it - a plush string sound and unhurried tempos, the equivalent of snuggling down into a leather armchair. The problem is that the performances sound too comfortable, too safe.

La valse, long a Mehta showpiece, is compelling, the dynamic ceiling stretched without compromising beauty of tone, the structure controlled and sophisticated, the onward motion spiralling headily.
