Pharrell Williams, One Direction, Florence And The Machine and Disclosure are among those headlining Apple Music in London this year, which will see the free concerts streamed live on iPhone, iPad, Apple TV and the company's all-new internet radio station Beats 1. Previously known as the iTunes Festival, the renamed Apple Music Festival will run across 10 days during September in London's Roundhouse venue.

As well as the rebrand to reflect the recent launch of Apple Music, the festival is also significantly shorter than the 30 days of free concerts which was previously held. Apple's Eddy Cue said: "We wanted to do something really special for music fans this year. The Apple Music Festival is a greatest hits set of ten unbelievable nights featuring some of the best performers on the planet appearing live and interacting directly with their fans on Connect and Beats 1."

Tickets for the concert are free but as usual only a very limited number are available and only to UK residents. Those looking to apply can do so through the Apple Music app or through iTunes. While the system is up-and-running on the app, there seems to be an issue on iTunes at the moment with an error message telling me "something has gone wry". Apple will also partner with the London Evening Standard newspaper to give away tickets to the shows while event discovery service YPlan is also offering users the chance to win tickets through its app and website.

The iTunes Festival started at London's Institute of Contemporary Arts in 2007, and has seen over 550 artists - including Adele, Beck, Coldplay, Elton John, Foo Fighters, Justin Timberlake, Kings of Leon, Lady Gaga, Katy Perry, Maroon 5, Muse and Sir Paul McCartney - perform in front of more than half a million fans.
