“A hurricane didn’t stop me getting here,” shouted Barry from Philadelphia, and there were plenty of hard core World Party fans for whom last night at the Albert Hall was a big deal concert – the first proper tour in 10 years, coming on the back of a brick-like five-CD box of unreleased material called Arkeology.

The Royal Albert Hall is pretty big. It's a prestige venue, but everything is relative. For the overwhelmingly French audience, the first British headlining show by Johnny Hallyday was the equivalent of seeing Paul McCartney, Tom Jones and Cliff Richard sharing a bill at the back room of the Dog & Duck.

There they are! It's The Beach Boys! They're playing "Wouldn't It Be Nice", halfway through their second set of the evening and it blossoms with harmonic beauty, with pop's finest, most glorious ambition. Sure, in the shadows behind them there are a bunch of session musicians carrying them. Particularly in the first half those guys made damn sure there was such a wall of vocals it would be hard to detect any flaws in the ageing voices (mostly around 70) of the original Beach Boys.

The past few years have seen the anniversary reissue, or concert tour in which classic albums are performed in their entirety, become something of a standard. Not so for Tori Amos, who this year is celebrating two decades since the US release of her debut solo album Little Earthquakes. To mark the occasion, she is instead collaborating with the Netherlands’ renowned Metropole Orchestra to rework and recreate some of her best-loved songs in an orchestral setting.

The BBC Proms are steeped in traditions, many admirable, some arcane, the odd one ever so slightly maddening. In the short life of The Arts Desk - we turned three on Sunday, the day after the 2012 Proms season came to a close - another tradition has come into being. Every year we publish a gallery of portraits of conductors at work. These astonishing photographs are all by Chris Christodoulou, who has been capturing the Proms in pictures for 31 years.

You’ve never seen so many people at a Prom, thousands of them packed into every space of the Albert Hall inside, while outside a 100-metre line of hopefuls queued in vain to stand in a pit where a small cat couldn’t have been added. But then this was a luxury Prom: with the Vienna Philharmonic and two musicians of golden integrity and sensitivity, lifetime members of the high table, the pianist Murray Perahia and the conductor Bernard Haitink playing two works born in Vienna.

If you’re going to bash a tam-tam for six, the Albert Hall is the perfect place to do it. The reverberation lasts for ages; and everyone in the audience can see you bashing. That must explain in part why Messiaen’s hieratic, gong-crazy Et expecto resurrectionem mortuorum has notched up 10 Prom performances in 45 years. Sunday’s was the first, though, to be performed by the historic and wonderful Leipzig Gewandhaus Orchestra, an outfit previously associated more with Bach and Mendelssohn than Messiaen’s idiosyncratic altar cloths in sound.

I'd love to see the stats on the last time a Prom was this packed for an afternoon organ recital. Were it not for the fact that organist Cameron Carpenter was sporting spandex trousers encrusted in silver glitter, a wife beater and Mohawk, you could have been mistaken for thinking we were back in the organ glory days of the early 19th century. Even the programme harked backward, offering as it did big, bloated Romantic transcriptions, arrangements and improvisations (pretty much everything in fact except the urtext).

Champagne on ice in the private boxes; scarcely any spare seats. This isn’t the normal situation for a concert climaxing in Witold Lutosławski’s Third Symphony, a modernist work whose usual audience is more than two men and a dog but still doesn’t pull in the crowds.

It's not completely unheard of what Sir Simon Rattle did at the start of last night's Prom, where he elided two familiar works - Ligeti's colouristic classic Atmosphères and the Prelude to Act One of Wagner's Lohengrin - into a seamless whole, beating without stopping from one into the other. But it was still pretty breathtaking.
