Unreleased recordings from the first ever recording session by punk pioneers The Clash are to finally see the light of day.
The tracks - along with other early studio sessions and unseen footage from shows at the start of their career - will come out this summer.
They will be part of a box set, Sound System, which draws together all their albums, rarities and tracks which did not feature on LPs.
The band made their first recordings at Beaconsfield Studios Buckinghamshire in 1976 with Julien Temple, the director who had befriended the band and went on to make The Sex Pistols movie The Great Rock And Roll Swindle.
Although the version of White Riot from the session went on to appear on the band's debut album, the versions of London's Burning and 1977 have not been released.
All five songs from their demo for label Polydor at the company's studio in Stratford Place, just off London's Oxford Street, are also included in the box set - three of which have never before been released.
Previously unseen footage from a 1977 show at Sussex University is also included in the package which will come out on September 9.
