THE BRITISH Summertime Festival has hosted some of the biggest names in music since its debut in 2013, from the Rolling Stones to Stevie Wonder and Taylor Swift.

This year's festival, which is underway and running until July 9, is a corker with the likes of The Killers and Kings of Leon taking to the stage. Here's all you need to know about 2017's event...

When is the British Summertime Festival on?

This year's festival promises two weekends of music with other events and activities, such as open-air movie nights and a street food market, scheduled in between.

The festival began on Friday, June 30 and runs until Sunday, July 9, 2017.

Which acts will be performing at British Summertime Festival 2017?

Phil Collins

Phil Collins headlined the opening show on Friday June 30, with a full supporting line-up, while American punk band Green Day headlined the Saturday July 1 show.

Former Genesis frontman Phil, 65, recently came out of retirement, selling out his comeback tour in just 15 minutes after announcing dates in the UK, France and Germany last June.

He said: “The reaction from the British public has been overwhelming. I can’t wait to play Hyde Park and see everyone there.”

Justin Bieber

Bieber fever was in the air on Sunday, July 2 when the Grammy Award-winning star took to the stage.

Justin Bieber will be returning to London next summer, following his Purpose Tour appearance at the O2 Arena this year.

After being embroiled in a miming scandal during his tour dates, the BST festival was a chance for the Canadian singer to win back the hearts of his British fans.

Green Day

The five-time Grammy-winning trio Green Day's new album Revolution Radio topped the UK charts when it was released last month.

Ahead of their performance at BST on Saturday, July 1, frontman Billie Joel Armstrong said the following: "London in the summer, us and tens of thousands of fans having the biggest party in one of the world's most legendary venues.

"We have the best year to look forward to and this has just made it extra special.”

Kings of Leon

Kings of Leon were the third big name act to announce that they would be headlining the summer festival on Thursday, July 6.

The Nashville quartet were supported by the Pixies, Nathaniel Rateliff and The Night Sweats.

Last month, the band played a secret gig in London and have recently gained top spot in the album charts, for the sixth consecutive time, with WALLS.

The band's drummer, Nathan Followill, said: “It’s always a pleasure to party with our amazing fans at Hyde Park."

Tom Petty and the Heartbreakers supported by Stevie Nicks

The legendary singer and his band will headline the event on Sunday July 9, their only European show of 2017.

The show will celebrate their 40th anniversary and will mark only their second UK visit in 18 years.

Petty and co will be joined by Fleetwood Mac singer Stevie Nicks and The Lumineers as support acts.

The Killers

The American quartet hailing from Las Vegas will take to the stage TONIGHT, Saturday July 8.

The gig will be their sole UK festival appearance this summer.

The band released their last album Battle Born four years ago, so fans will be hoping new music is released ahead of the concert.

Support acts on the day include Elbow and White Lies.
