If music writers love to place artists in genres, it is a more-than-usually fruitless task with Magnetic Fields, the brainchild of “composer, multi-instrumentalist and bubblegum purist” Stephin Merritt. Many people discovered Magnetic Fields (named after the surrealist André Breton’s novel Les Champs Magnetiques) with their 3-CD box set 69 Songs, which was released in 1999. The titles themselves suggested some of his musical playgrounds, such as “Punk Love”, “Love is Like Jazz” or “World Love”. Others referred sometimes obliquely to Billie Holliday, Orchestral Manoeuvres in the Dark, Fleetwood Mac or Irving Berlin. Merritt said that the album “was not remotely an album about love. It’s an album about love songs, which are very far away from anything to do with love”.

As one who came to know the B minor Mass singing in a clogged, 150-strong choir, I welcomed the authentic-movement rush in the 1980s to  whittle it down to What Bach Might Have Wanted (if, indeed, he had lived to hear his ideal religious compendium performed in its entirety). For a while, it shrivelled to anorexic dimensions in the shape of Joshua Rifkin's one-voice-per-choral-line hypothesis.

What would you imagine the composer John Adams might choose to conduct – apart, that is, from a little something he himself made earlier? Well, the first of two London Symphony Orchestra concerts this week brought no big surprises: Sibelius’ Sixth Symphony was in essence a little like returning to his minimalist roots – a bunch of insistent melodic cells and dancing ostinati. Flanking it, as if to reassert that everything Adams writes is essentially operatic, was orchestral music born of opera: Adams’ own Doctor Atomic Symphony and the “Four Sea Interludes” from Britten’s Peter Grimes. Adams, the conductor, had his work cut out.

In every partnership there is a leader, and it’s not always the featured name. While the hall was packed with Ma followers for this rare cello-and-piano recital, what emerged was a richly sensitising foretaste of what the Emanuel Ax residency is going to offer over the next fortnight. This is one marvellous pianist.

It has always been a cornerstone of my personal philosophy that beauty and insight can be found in the very lowest of common denominators. That Big Brother, Friends, Love It magazine or Paris Hilton provide revelations about life that are of as much consequence, of as much wonder, as any offered up by the classic pantheon. That that which the people respond to must and usually does have plenty of merit lurking within it.
