To keep a string quartet on the road for 20 years requires patience, devotion and staying power. Therefore the Wigmore Hall's participation in the celebrations of the 20th anniversary of the Belcea Quartet, which is being marked in several European concert halls, is fitting testimony to the achievements of these players. Last night's concert was the first of their London series.

This was Henryk Górecki beyond the Third Symphony. His otherwise ubiquitous masterpiece was notable by its absence from yesterday's programme. That was surely a conscious decision, and a wise one, allowing his many other important works to come out from its shadow. Górecki turned out to be an ideal subject for the BBC Symphony Orchestra’s “Total Immersion” treatment. His music gradually evolved throughout his career, from acerbic neoclassicism, to esoteric serialism, and then to austere minimalism.

Nelson Goerner has settled rather gloriously into being a musicians’ musician. An artist of this calibre should be selling out the Wigmore Hall – but it wasn’t his fault that yesterday was Monday, and the pianophiles who turned out to hear him were rewarded with a rich and satisfying programme.

Performances of Mahler’s Tenth Symphony are rare, at least in Scotland. The programme note for this series of concerts by the BBC Scottish Symphony Orchestra records that the orchestra’s only previous performance was in 1978. Those I spoke to in the audience in the Usher Hall could not recall a performance by Scotland’s other symphony orchestra, the Royal Scottish National Orchestra (or SNO as it was previously), since way before that.

In 2007, Jiří Bělohlávek set the distinctive seal on his leadership of the BBC Symphony Orchestra and their ongoing Mahler cycle with a riveting performance of the Third Symphony. The legacy he established of a deep, well-moulded string sound which the orchestra didn’t really have before has left its mark on his successor Sakari Oramo’s even more impassioned attempt at the most epic of all Mahler’s symphonies.

Cards on the table: the City of Birmingham Symphony Orchestra is looking for a new music director. Having filled its new season with emerging talents – Andrew Gourlay, Daniele Rustioni, Ryan Wigglesworth and Ben Gernon, to name just four – it’s an open secret that any concert directed by a youngish, more-or-less unattached conductor in Birmingham for the foreseeable future is effectively an audition for the job. And don’t let anyone tell you otherwise.

Nothing will ever test the depth, breadth and sheer virtuosity of a large orchestra more than Mahler’s symphonies. It’s hardly surprising, then, that the two unsurpassable concert experiences, for me, have been Bernstein’s Mahler Five at the Proms and Abbado’s Lucerne Festival Ninth, or that the two London orchestras with the most consistently challenging conductors, the LPO under Vladimir Jurowski and the BBC Symphony Orchestra with Sakari Oramo, have chosen to open their new seasons with the two most experimental of the 10 symphonies on consecutive nights.

Mark Wigglesworth and I go back quite a long way in terms of meetings – namely to 1996, when I interviewed him for Gramophone about the launch of his Shostakovich symphonies cycle on BIS. He completed it a decade later, though that release hung fire until last year. We should have discussed the whole project shortly afterwards, but despite his generously coming to talk to the students in what was then my Opera in Focus class about Parsifal, which we were studying, I wasn’t able to keep my part of the bargain.

The frail bridge between Baroque and Classical aesthetics was the theme for this debut UK appearance by Insula, the period-orchestra extension to Laurence Equilbey’s superb vocal ensemble accentus.
