Blur are going to debut two new songs on Twitter.
The band will play the tracks, which have not been performed in public, in a live web stream on the social networking site on Monday July 2.
It comes ahead of the brit-pop band's appearance at London's Hyde Park in August, in a show to mark the close of the Olympics.
The foursome, who reunited in 2009, will play Under The Westway and The Puritan from a secret location in the UK and the songs will then be available to download.
Blur frontman Damon Albarn said: "I wrote these songs for Hyde Park and I'm really excited about getting out there and playing them for people."
The group are also playing warm-up dates in August at Margate Winter Gardens, Wolverhampton Civic Hall and Plymouth Pavilions.
