U.K. rock act Blur will reform for an open-air show in London's Hyde Park next summer. The band has been on hiatus following the campaign for its album "Think Tank" (Parlophone).

The Hyde Park show takes place on July 3 and is promoted by Live Nation and Metropolis Music, in association with CMO management and booking agent X-Ray Touring.

Guitarist Graham Coxon, who quit the band for a solo career in 2002, has signed up to the reunion, which features the full original lineup of frontman Damon Albarn, drummer Dave Rowntree and bassist Alex James.

There has also been speculation in U.K tabloid the Sun that Blur will headline the Glastonbury festival in June, but there has been no official confirmation.

Coxon last performed with Blur in 2000 at London's Royal Festival Hall. While he has focused on solo albums, Albarn has worked on several projects outside Blur, including the animated group Gorillaz and the Mandarin language opera, "Monkey: Journey To The West."

The band, which formed 20 years ago, released seven studio albums, five of them reaching No. 1 in the U.K.
