Paris - The mystery surrounding Daft Punk, the Grammy-winning French musical duo who usually keep their faces hidden in robot helmets, will be lifted a little more in a new television documentary to premiere next week.

Daft Punk Unchained, made by BBC Worldwide France and to be shown on France's Canal+ network next Tuesday, uses rare archive footage and interviews with friends, producers, journalists, DJs and high-profile fellow artists such as Pharrell Williams and Kanye West to trace the rise of the pair who made 2013's global hit Get Lucky.

The two members of Daft Punk, Thomas Bangalter and Guy-Manuel de Homem Christo, gave unprecedented approval for the 85-minute documentary.

Although they are normally reluctant to talk to the media, their voices are heard in excerpts from rare past interviews.

"We have daily lives that are a lot more normal than the lives of artists who have the same level of fame as us but who might be attached to being physically recognised," Bangalter says in one excerpt. At the other end of the spectrum, the documentary shows Williams and West, two big music stars who have worked with Daft Punk but who actively court celebrity.
