A nationwide tour opening in the Boston area is exciting enough, but when the group opening their tour here next week is Dead & Company, well, that's even better.

Indeed, the jam-band supergroup, featuring members of The Grateful Dead, Allman Brothers Band and Ratdog, as well as John Mayer, will open their three-month, 26-date summer tour Wednesday, May 30, at Xfinity Center in Mansfield.

The group features Mayer and Grateful Dead alum Bob Weir on lead and rhythm guitars and lead/backing vocals, Grateful Dead alumni Mickey Hart and Bill Kreutzmann on drums and percussion, Allman Brothers Band alum Oteil Burbridge on bass guitar and percussion, and Jeff Chimenti of Ratdog on keyboards.

Dead & Company did four shows in the Bay State last year, two dates at Fenway Park in June and two nights at TD Garden in November.

Though Xfinity Center is a smaller venue than Fenway Park, the group is doing some larger venues on this tour, including two dates at Citi Field in New York and a date at Autzen Stadium in Eugene, Ore., at the University of Oregon in June, a single show at Dodger Stadium in Los Angeles and two dates at Folson Field at the University of Colorado in July.

Deadheads who either miss the show next week or just want to catch them a second time can see them at Xfinity Theatre in Hartford on June 13.

The genesis of Dead & Company came in 2015, when Mayer was guest-hosting "The Late Late Show" and invited Weir to join him in a studio performance.


They bonded, and while Weir, Hart, Kreutzmann and Phil Lesh rehearsed for the Fare Thee Well series of shows to mark the Grateful Dead's 50th anniversary, Mayer began practicing the band's catalog of songs. A few months later, in August 2015, Dead & Company was formed.

It started with a single concert, on Halloween 2015, at Madison Square Garden, but a full tour followed through the end of the year. The band embarked on full summer tours in 2016 and 2017 and the fall tour last year, but has yet to release any new music.

Because the group has The Grateful Dead as its pedigree, it's impossible to know what the band will play, but that's part of the magic of the experience. Anything and everything are fair game, particularly as the band has hundreds of shows under its belt at this point.

Enjoy the show.
