The Dead [ tickets ]--a group that features the four surviving members of the Grateful Dead--will be joined by Bob Dylan [ tickets ] on the second leg of their summer tour.

The Grateful Dead [ tickets ] and Bob Dylan last co-headlined when they toured the stadium circuit in 1987, according to the Dead's publicist. Dylan and his band will join the Dead from July 29 through Aug. 10; confirmed dates are listed below, and more will be announced.

The Dead's tour, dubbed "Summer Getaway 2003," is scheduled to get underway at Tennessee's Bonnaroo Festival on June 15. The first leg runs through July 8, and includes a July 4 stop at Willie Nelson's annual "picnic" show in Austin, Texas.

Singer-songwriter Joan Osborne [ tickets ] will handle some of the vocals on at all of the Dead's summer shows. Steve Winwood will be on the bill from June 17 through June 25, and Willie Nelson supports from June 27 through July 2.

Dylan, Willie Nelson, and Steve Winwood will appear with their own bands and will sit in with the Dead during each of their respective shows.

The Dead's lineup includes Grateful Dead members Mickey Hart and Bill Kreutzmann (both on percussion), Phil Lesh (on bass) and Bob Weir (vocals and guitar).

It falls to guitarist Jimmy Herring--who paid his jam-band dues over the last dozen years by playing in Col. Bruce Hampton's Aquarium Rescue Unit, Jazz is Dead and the Allman Brothers Band--to fill the void left by late Grateful Dead guitarist Jerry Garcia.

Rounding out the group are Jeff Chimenti (from Weir's Ratdog [ tickets ]) on keyboards and Rob Barraco (from Phil Lesh and Friends) on keyboards and vocals.

In August of 2002, the surviving members of the Grateful Dead performed together for the first time since the death of Jerry Garcia during an event at the Alpine Valley Music Theatre in East Troy, Wis. Earlier this year, they changed their name from the Other Ones to the Dead.

The Grateful Dead performed their last show in Chicago on July 9, 1995. Singer-guitarist Garcia died a month later in California after he suffered a heart attack at a substance-abuse treatment facility.

Bob Weir's Ratdog is currently in the midst of a spring tour, and Dylan opens a headlining tour later this month.
