Air: Your views

Where will Air go next?

French electro-pop duo Air burst onto the music scene in 1998 and have sold 2 million copies of their debut album Moon Safari.

Now they are back with a new, darker venture into prog rock territory.

"Darker and less immediate than its predecessor, 10,000 Hz Legend is an album which takes time to work its magic," wrote the BBC's Nigel Packer.

But what do you think? After the lightness of Moon Safari, is their new album too inaccessible? Is this a step backwards for the band or is the best still yet to come?
