Twenty-five years ago, a-ha achieved something unprecedented for a Norwegian band: they entered the British charts. The week of 5 October, 1985 saw “Take On Me” enter the Top 40. Three weeks later it peaked at number two. To mark the anniversary, a-ha have chosen to do two things: embark on a worldwide farewell tour and play a special show at the Royal Albert Hall, running through their debut album, Hunting High and Low, with a full orchestra. That not being enough for a full show, they also played its follow-up, Scoundrel Days.

It must have been with a leaden heart that the BBC Proms planning team realised that 2010's Last Night would fall plumb on 9/11. How to reconcile all the traditional Brit triumphalism and singing of Jerusalem with the rather more contemporary need to reconcile all, whether out of Jerusalem or not? They did, and full marks for a delicate balancing-act of culture politics and a moving occasion last night (admitted by one who had spent a lifetime avoiding the Last Night of the Proms).

Chris Christodoulou has been honing his focus on conductors in past Proms seasons to wonderful effect, but this year has produced a galaxy of master portraits that outdoes even the immortal cartoons of Gerard Hoffnung in entertainment value. We’ve featured many of them throughout our reviews of two months of Proms. Here Chris makes his selection of favourites. Click on a picture to enter the slideshow.

Monteverdi’s 1610 Vespers are something of a musical enigma. Neither their true pitch nor order of movements, their origins, nor even whether they were intended as a complete sequence is known for certain, prompting scholar Denis Arnold to conclude that, “to perform it is to court disaster”. Such a grim augury however has done little to discourage musicians, and in this, their 400th anniversary year, Monteverdi’s Vespers have been ubiquitous.

It was one of those moments that every conductor (and orchestra) dreads: “The Procession of the Sage” from Stravinsky’s The Rite of Spring is in rip-roaring full cry, percussion grinding and scratching, high trumpet screeching – but Daniele Gatti, it would seem, loses a bar somewhere and gives his Orchestre National de France a premature cut-off, leaving the entire brass section between a rock and a hard place. Stop or play on? An ignominious collapse ensues – as big a blunder as I’ve heard in any professional concert in years. Who says The Rite of Spring no longer has the capacity to shock?

One Proms blockbuster effortlessly reached its goal last night when Paul Lewis crowned his Beethoven piano concertos series with a diamantine "Emperor". Two more suggested themselves in a challenging quartet of big works programmed by the Royal Scottish National Orchestra's brilliant music director Stéphane Denève. I now hunger for concert performances here conducted by Denève of Berlioz's Benvenuto Cellini and James MacMillan's The Sacrifice. On the evidence of the late-night Prom's box of delights, I even uncharacteristically want to hear all of Vivaldi's Orlando furioso with Philippe Jaroussky and Marie-Nicole Lemieux as the stars.

My abiding memory of the Berlin Philharmonic’s second Prom under Sir Simon Rattle on Saturday will be of 6,000 people listening with rapt, or at any rate silent, concentration to Schoenberg, Webern and Berg. Has it ever happened before?

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?

From the cuckoo hidden somewhere in the Albert Hall thicket to the Wagnerian bacchanalia of a rollicking Witch's Ride, Glyndebourne adapted its queasy little fairy tale to the widescreen of the Proms with its usual style. There was a twist or two to the consumerist heaven and hell of Laurent Pelly's never too heavy-handed production as semi-staged by assistant director Stéphane Marlot. And centre-platform rather than down in the pit, the phenomenally gifted Robin Ticciati played Peter Pan to the best possible pair of "children", helping them to soar in Albertspace with effortless charm.
