MARTIN HOYLE Death and intimations of mortality dominated Wednesday's prom. The result, far from being depressing, was sombrely exhilarating - for the second, massive item was Mahler's Ninth Symphony, opening with the rhythmic figures referring to the composer's own heart ailment and permeated by awareness of his recently deceased daughter.

The concert opened with Gyorgy Kurtag's Stele, in memory of his teacher. Its 15 minutes offer a test in gradations in dynamics and tone for any orchestra: grief vocalised from anguish to wistful regret and everything in between. The BBC Scottish Symphony Orchestra again proved superbly controlled: no exaggeration either of overblown emotion or stiff upper lip.

That Ilan Volkov has produced a wonderfully drilled body of players was confirmed by the Mahler. Here the temptation is to splurge out in garish colours. It is all too easy to wallow in late-Viennese decadence, neurosis, nostalgia and necrophilia, but Mahler looks forward, and the abyss of the twentieth century's more abrasive excesses seems just around the corner. Volkov kept a firm rein and the emotions were the more powerful for never bursting the banks of musical decorum: refined phrasing, hushed intimacy (not always the first consideration in Mahler) and an awareness of overall form that unfailingly kept the 80-minute work from sprawling.

The BBC SSO have turned into a crack orchestra. They're back down south on August 14 and 16 - the latter programme with a Scottish opener from James MacMillan. But any sneaking London ideas that this orchestra might be best suited to its home product have been brilliantly contradicted by the band's two proms so far this season.
