To celebrate the 50th anniversary of Grateful Dead, Mickey Hart, Bill Kreutzmann, Phil Lesh, and Bob Weir will reunite at Chicago's Soldier Field, nearly 20 years to the day from the last Grateful Dead concert with Jerry Garcia, which took place at the same venue.

Garcia died a month later following a heart attack.

"Fare Thee Well: Celebrating 50 Years of Grateful Dead" will occur over three nights on July 3, 4, and 5, 2015, marking the original members' last-ever performance together. The band will be joined by Trey Anastasio (guitar), Jeff Chimenti (keyboards), and Bruce Hornsby (piano).

The group will perform two sets of music each night.
