The four surviving original members of the Grateful Dead plan to reunite in July for three performances in Chicago that are billed as the band’s final shows.

The July 3-5 shows at Soldier Field will mark the 20th anniversary of the band’s last performance with guitarist Jerry Garcia, who died in 1995. It will also mark the 50th anniversary of the band’s formation in San Francisco.

Dead members Bob Weir, Phil Lesh, Bill Kreutzmann and Mickey Hart will be joined for the “Fare Thee Well: Celebrating 50 Years of the Grateful Dead” concerts by Phish guitarist Trey Anastasio, keyboardist Jeff Chimenti and pianist Bruce Hornsby.

““This is the band that caused so much to happen, that led to the creation of so many bands that have been influenced by what they achieved, both musically and culturally,” said “Fare Thee Well” producer Peter Shapiro. “The Grateful Dead truly are the great American rock ‘n’ roll band, so to have their final shows take place July 4th weekend in Chicago creates a lot of potential for magic to be made.”

There’s no word yet on any plans for a TV special or homevid release for the shows.
