Chris Martin's new military style
Coldplay have marked their live return with a free gig in London.
The band played at the 5000 capacity Brixton Academy for competition winners from the band's website.
On top of new material like latest single Violet Hill, Coldplay's set included some of their biggest hits like Trouble, Clocks and Yellow.
Coldplay's new album, Viva La Vida Or Death And All His Friends topped the charts at the weekend after being on sale for just four days.
Between the day of release on 12 June and Sunday 15 June, it sold 302,000 copies, outselling the top five biggest selling albums of the week, combined.
The figures make Viva La Vida Coldplay's fastest-selling album to date.
Viva La Vida
The gig was a fairly short and sweet affair.
Coming in at just over an hour long, it was a mix of material from the band's four studio albums.
Dressed in their new military style jackets, the band kicked things off with the opening track from the new album, Life In Technicolour.
A particularly boisterous Chris Martin dedicated the album's title track Viva La Vida to "anyone who felt like they were going to lose".
Its football terrace chant raised the roof as Martin bounded around the stage.
25-year-old Rosie from Cheshire said: "I've never seen him as such a performer before, he was going wild.
"It's more experimental the new stuff.
"I think the more I hear it, the more I'll like it, I'm just so pleased they're back"

At one point, the band, having disappeared from the stage, re-appeared on the balcony where they launched into an acoustic version of Yellow.
Drummer Will Champion then took lead vocals for a version of Death Will Never Conquer.
18-year-old Ed from Stafford said: "I thought they were brilliant, new stuff and old stuff as well.
His mate, 18-year-old Chris, also from Stafford continued: "I think I preferred the old classics.
"The new ones aren't quite up there with the old ones."
By the time Coldplay were back on stage for the encore of Fix You, a huge flag bearing the word VIDA had unfurled behind them.
During the last song of the night, Lovers In Japan, two cannons showered the audience with red, white and blue paper butterflies.
26-year-old Catherine from London said: "There were a lot more drums and it's a lot more more rocky.
"I'm up for it. It was brilliant."
