Reunited Blur are to debut new songs on Twitter.
The band will play two new tracks - which have not been performed in public - in a live web stream next week.
The performance on Monday comes ahead of their appearance at London's Hyde Park in August, in a show to mark the close of the Olympics.
The quartet will play Under The Westway and The Puritan from a secret location in the UK.
The songs will later be available to download and a limited edition 7in single will be released by Parlophone on August 6.
The live stream takes place on Twitter at 6.15pm on July 2 at blurofficial. There will also be an interview with the band.
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.
