Chris Martin's children don't listen to Coldplay.

The band's frontman wants his kids - daughter Apple, seven, and son Moses, five, with wife Gwyneth Paltrow - to be "proud" of his musical achievements, but he doesn't force his family to listen to his songs.

He told the USA Today newspaper: "My children made me focused on not wasting time on anything I don't think is worth wasting time on.

"So that's affected my editing process. You don't want to spend months and months doing something and have it turn out terrible. You want your kids to be proud, basically. So it gives you extra drive."

Meanwhile, Coldplay have announced they will be streaming a live show - directed by award-winning filmmaker Anton Corbijn - from the Plaza de Toros de Las Ventas arena in Madrid, Spain, as part of the 'American Express Unstaged' livestream music series.

Chris said: "Anton Corbijn has been a big hero to us for a long, long time so we're thrilled to be beaming this concert out to the world through his cinematic lens.

"We can't wait to share this experience with him and with all of our fans watching 'American Express Unstaged' around the world. It's going to be special."

The 2011 'American Express Unstaged' performance will be live-streamed at 4pm ET and 1pm PT on October 26 at
