The interior world of Morocco seems a magical place where music and words have more power than in the disenchanted, cold light of the North. On the plane on my first trip to Fes I met a businessman, in import-export, wearing a Burton suit. The strangeness of Morocco revealed itself when he started telling me of his current problem, that his daughter has been put under a spell by a djinn (he translated the word as “devil”) residing in a frog. His mother was a member of the Hamdashas, sects who are known to cut themselves, and his grandmother, he said, drank boiling water when under trance. Some djinns are believers, are harmless; others, the non-believers (like the one causing trouble to the businessman’s daughter), are the ones that cause lots of trouble.

You forget how fast the night descends in the tropics, in half an hour the light goes, the sun disappearing with a grand melodramatic finality. You understand the Mexican tribe who believe without their prayers it will never rise again. But it leaves behind a warmth in the enveloping womblike darkness. With the breeze against our faces in the Bahian night, Brazil’s most celebrated pop star is showing me his domain, a fabulous clifftop house in Salvador de Bahia in the state in the North-East coast where Cabral’s boat came ashore half a millennium ago, and where Caetano Veloso was born 67 years ago.

"It was only on Monday afternoon that the final scores of three of the movements were put into my hands," says Sir Simon Rattle, chuckling at the memory and casting a mock glance of disapproval at the composer and trumpeter Wynton Marsalis who is sitting next to him looking rather sheepish. "It makes us realise that composers are human beings just like we are," the conductor adds. "I'm just praying I get all my tempos right by tonight."

Brilliant though it was to be shooting an Imagine film for BBC One, we did experience the occasional tremor of foreboding about making a programme with Nigel Kennedy. We (that's me and director Frank Hanly) had a bit of previous with Nigel - I'd done several print interviews with him, and we'd shot a couple of short films with him for EMI.

With Fela Kuti's old band playing Brighton this evening fronted by his son Seun and on the same bill as Tony Allen, the drummer who co-created the increasingly influential Afro-beat sound, it seemed a good excuse to revisit the first interview I ever got published, which was with the great African pop star in 1984 (in Blitz magazine, also a version for the Observer). A polygamist, with at one point 28 wives, a political and musical revolutionary, Fela was one of the most extraordinary musicians ever to walk the planet.

Rokia Traoré has always seemed most comfortable creating at trysting points, darting between different worlds without ever quite belonging to any one of them. The daughter of a Malian diplomat, as a child her favourite locations were airports, “this middle point between two places; the idea of leaving a place to go to another one was the most interesting part of my childhood”.

Laurie Anderson's new show Delusion opens at the Barbican in London next week. Since the late 1960s she has been at the forefront of artistic innovation. From early pieces where she appeared in art galleries (wearing ice-skates in a block of ice that slowly melted), to her epic opera United States I-IV, she has carved out a niche as something between a poet, artist, technician, humourist, pop star and magician. We chatted over a coffee for breakfast in Paris last week, after I had seen Delusion the previous night.
