As Mahler symphonies rain down from heaven - or flare up from hell, according to your viewpoint - in this second anniversary year, it's wise to choose carefully. But why earmark Jiří Bělohlávek's performance of the Sixth above the likes of Gergiev, Dudamel, Jurowski or Maazel? Because he's been working his way through the cycle with his BBC orchestra at the careful rate of one a year; because he knows what space to give, and what colours to draw; and above all, because he refuses to batter our hearts too fiercely too soon - crucial for the most insistent tragic chapter in Mahler's symphonic chronicle.

It was with Mahler’s Opus 1 – folkloric cantata Das klagende lied – that Vladimir Jurowski so memorably launched his role as the LPO’s principal conductor, and it was to this work that he returned last night. Four years on and he asked his audience to consider it within a rather different narrative; in lieu of an arc of Germanic development, moving from Wagner’s Parsifal Prelude to Berg’s Three Pieces for Orchestra, Jurowski instead framed it with Hungarian works from Bartók and Ligeti. While the dialogue between these three exploratory pieces may have been more oblique, Jurowski’s highly coloured reading of the Mahler remained briskly direct.

Believe it or not, some critics can't get enough of London's superabundant concert scene. I could hardly be sour about not catching Gustavo Dudamel's first Barbican concert on Thursday night, spellbound as I was by his predecessor at the Los Angeles Philharmonic, Esa-Pekka Salonen, spinning such insidiously beautiful Bartók with the Philharmonia over on the South Bank.

Most of us don't object to experiments in concert presentation - the occasional one-off showcase to lure the young and suspicious into the arcane world of attentive concert-going, the odd multimedia event as icing on the cake. It's only those pundits obsessed with the key word "accessibility" who tell us that the basic concept of sitting (or standing, as they have at the Proms for well over a century) and listening with respect for those around us needs overhauling. It's a typical journalistic conception of "either/or" instead of "all approaches welcome" - a case of what an American academic I know calls "bad binaries".

Despite footsteps in the snow, as creepily characterised by Debussy's prelude of the same name, and sleighbells to launch a childlike symphonic journey, interior illumination should have been at the core of this concert. Sadly, given Colin Matthews's refined but fussy designer lighting in his Debussy orchestrations, a low-wattage Rimbaud/Britten zoo from one-tone soprano Christine Schäfer and hard sunbeams failing to probe the inner mysteries of the tomb-effigies Mahler envisaged in his Fourth Symphony's slow movement, it wasn't. Fortunately Vladimir Jurowski found novelty enough elsewhere to keep us from slumping in the semi-dark.

From primeval baying to a very human song in excelsis, Mahler's Third Symphony cries out for Olympian interpretation. That I've found in recent years with Abbado in Lucerne and the Albert Hall, Bělohlávek at the Barbican and Salonen on the South Bank. Since Vladimir Jurowski always demonstrates fresh thinking, and sometimes a burning intensity to match, the first performance of his London Philharmonic's new season was bound to be at least as challenging.

Call me a paradoxically wary old Mahler nut, but I reckon that given 24 months of anniversary overkill, it might keep things fresh to catch each of the symphonies live no more than once a year. So, having heard an Everest of a First Symphony from Abbado in Lucerne last August, I thought Rattle's might be the team likeliest to do this far-from-beginner's symphony similar justice. Did its Proms Mahler One compare well with the Swiss festival love-in?
