The four surviving members of legendary rock band the Grateful Dead are set to reunite this July for a series of concerts in Chicago. The shows will celebrate the band's 50th anniversary and mark their first performance together since 2008.

The reunion will feature the band's remaining members, Mickey Hart, Bill Kreutzmann, Phil Lesh and Bob Weir. While three unconfirmed guests will be drafted in to replace frontman Jerry Garcia who died 20 years ago.

The last show the band played with Garcia before his death in August 1995 was Chicago's Solider Field stadium, home of the Chicago Bears. Garcia’s death ended the tradition among the band’s ‘deadhead’ fans, which saw them travel from show to show and swap bootleg recordings.

“It is with respect and gratitude that we reconvene the Dead one last time to celebrate - not merely the band's legacy, but also the community that we’ve been playing to, and with, for 50 years," said bassist Phil Lesh in a statement.

"Being able to get everyone together - the fans and the band members - for a special weekend is a really big deal," added Garcia's daughter, Trixie.
