Watch AR Rahman and his troupe make music with strange gestures and some help from Intel

It's either creepy or cool, depending on your perspective.

On Wednesday A R Rahman, along with other musicians, played a curious gig at the Consumer Electronics Show on in Las Vegas.

As the video of the performance demonstrates, we can hear the music, but can't see any actual instruments being played.

What's making the music then? The white bands on the musicians arms and legs.

These bands have embedded within them Intel's Curie, a button-sized computer with which Intel wants to revolutionise wearable technology.

Announcing the performance, Intel's CEO Brian Kraznich said, "We gave him (Rahman) Intel Curie and let his imagination run wild, to transform the experience of music."

Rahman, a keytar slung over his shoulders, was accompanied by the famous percussionist Sivamani, and three other musicians, all making music through gestures. The opening demonstration of gesture music was followed by Rahman's Slumdog Millionaire track Jai Ho – played entirely through gestures here, and a group of singers.

Explaining the technology, Rahman said, "The bands have Intel Curie technology and it senses my gestures and transfers that into mini data; it goes to the computer on one of the softwares (sic) and changes that into music."

Not everyone enjoyed the show however. One publication gave it a scathing review, calling it the opposite of rock n' roll.

Many others enjoyed it, though.

Rahman's performance ended Intel's keynote at the CES 2016, the annual showcase of advances in consumer technology. Intel had unveiled Curie at last year's show, and returned this year to demonstrate how the little computer can be used to influence and advance sports, health and art.

The keynote included demonstrations of other products too – a hoverboard that transforms into a robot, drones that can dodge trees and other obstacles, and trainers, besides other sporting equipment.

One more thing. There is also a mysterious tie-up with Lady Gaga.
