A hand gestures for me to join a circle of crouching Tuareg tribeswomen. In the centre is a wooden drum whose loping rhythm sets the beat for a melody sung by a teenage girl.

In the sunset I notice several plumes of sand on the edge of the massive desert plateau. It’s the young blades, dressed to kill in indigo veils and robes, racing in on camelback towards the circles of singers, cutting each other up on the way.

The camels then take up a prancing gait and follow the rhythm of of the Tinde drum, circling the group. So it’s true, the camels dance at the Festival in the Desert.

I had first come to the north of Mali in January 2001 with a French group, Lojo. The area had been cut off from the rest of the world for years because of the Tuareg rebellion, the result of a history of distrust between ethnic groups exacerbated by poverty and drought. The legendary rebel group Tinariwen was due to headline an event showcasing Tuareg culture; behind the scenes, government ministers were offering camels for Kalashnikovs handed over by ex-combatants.

The remoteness, and the sublime blank canvas of the desert, turned the first festival into a surreal and haphazard event. Attended by 50 Westerners and 1,000 nomads, it had none of the infrastructure of a Glastonbury, but a magic that was lit by the eerie glow from a full lunar eclipse in the freezing Saharan night.

I found myself acting as an informal stage manager, venturing in total darkness into nomadic tents and inquiring in schoolboy French: “Excuse me, are you the griots from Timbuktu? Because if you are, you’re on in ten minutes!”

We had limited amounts of diesel to run the generator feeding the PA, so if a group got overenthusiastic and stayed on stage too long, it cut into the perfomance of others. One performer who felt he had had to wait too long took matters into his own hands, jumped on stage and executed a wild sword dance of such ferocity that he took control of the show and brought the musicians to a clattering standstill. I played a short set (wary of such techniques) with a pickup band of French and Tuareg musicians, one of whom arrived on the stage directly from a camel. My strangest dreams seem more real in retrospect.

I came back from my first trip to the desert broke but happy and when I got a call from Robert Plant asking if I would like to work with him, I told him all about my adventures. “When you next go, I’d love to come with you,” he said.

Three years later I found myself pushing a Toyota Land Cruiser out of soft sand on my way to a gig with Plant near Timbuktu. A veteran of desert trips to Morocco, and a kindred spirit in terms of flipping between cassettes of wailing Berber music and raw 1920s blues from Charlie Patton, Plant had fallen for Tinariwen and Tuareg music. Their hypnotic trance-blues spirit had become a touchstone for our work together.

We were billeted in a traditional tent and unpacked our sleeping bags on to the reed mats. I had warned my travelling companions to be ready for sand getting in every orifice, for goat meat with the consistency of a human ear, and for toilet facilities along the lines of “go forth and dig, keep an eye out for the scorpions”.

But I was amazed by how the organisers had developed the festival. There was cold beer and chips, a merchandise stall, a huge stage and lights, and even a shower, albeit a trickle. The Westerners were in their hundreds, but the event was dominated by magnificent Tuareg camel riders, striking poses on top of the dunes. We got straight into rehearsals.

We were half way into a version of Whole Lotta Love with acoustic guitars and hand drums in our tent, when our next-door neighbours, a group of Tuareg girls, stunning in indigo and gold, gatecrashed our rehearsal. The way they started to move to the rhythm made the distance between tribal dance and rock’n’roll disappear. Later, after they had disappeared, a group of young camel riders pulled up to our tent. “Where are the girls?”, they demanded. “ Elles sont parties,” we managed, and they galloped off.

As darkness fell on the final night of the festival it was time for our show. The view from the stage was unforgettable. Ranks of Tuareg elders in their finery outnumbered the Westerners, all looking unkempt, but there was a common knowledge that we were sharing something special. Our set was followed by a masterly performance from the great Ali Farka Touré, whose music rolled as effortlessly as the River Niger.

Afterwards we piled into a four-wheel drive vehicle and joined a convoy of 40 cars racing through the desert night. We crossed the Niger at dawn, hippos lolling not far from our little ferry, and eight bone-shaking hours later, we were in Mopti, ready to fly home.

Weeks later I was still finding sand in everything. The Sahara was calling me back. Aman Iman: Water is Life is the new CD by Tinariwen (Independiente, £15.99)
