LPO, David Murphy, Royal Festival Hall

A packed Festival Hall and a cheering, stamping, standing ovation – hardly the usual welcome for an evening of contemporary music. Sitting, wizened and waistcoat-clad, at the centre of the front row was the reason: Ravi Shankar. Framed by the mathematical minimalism of John Adams’ Shaker Loops and Philip Glass’s Violin Concerto No. 1, Shankar’s first-ever symphony was last night given its world premiere by the London Philharmonic Orchestra.

In general, I’m no particular fan of composers talking in public about their own music. My family suggests that this is because I’m hoping to get the job of talking about it myself. But the real reason is that, on the whole, composers don’t tell the truth about their work – and indeed why should they? Creative work is a mysterious and impenetrable process, and it’s a very modern, right-to-know sort of assumption that those who do it should also be able to explain it. Probably nobody is.
