NEW YORK CITY—Grateful Dead and John Mayer fans rejoice in sheer delight, as 10,000 tickets will be awarded randomly for the November 7 concert in New York City’s Madison Square Garden.

Grateful Dead’s guitarist Bob Weir and drummers Mickey Hart and Bill Kretuzmann united with John Mayer to create Dead & Company. The original Grateful Dead bassist Phil Lesh is not part of Dead & Company.

Together as one, Dead & Company announced Monday that 5,000 fans will be given the opportunity to win two tickets each to the New York City show. No tickets will be sold for the performance. Instead, fans can enter to win the ticket giveaway between Monday, October 5 through Thursday, October 8 on Dead & Company’s website.

Dead & Company will embark on a 23-date national tour that kicks off on October 29 in Albany, New York with two consecutive shows at The Forum in Los Angeles towards the end of December.

The group has teamed up with American Express for the “American Express Unstaged” music series sweepstakes. The concert will also be streamed live with the help of film director Brett Ratner.

In an interview with the Associated Press, Bob Weir expressed his excitement about the free concert saying, “People who want to hear the music get to hear it for free and we get to promote our music and share it with people.”

He also discussed how preparation for the concert has been going. “We’re about halfway in and rehearsals are going well, if I may say so,” Weir explained. “We’ve been through 45 or 50 tunes and I’m not going to tell you that we have them entirely locked down, but we have a good handle on them.”

The band is asking fans who will either watch the live stream or attend the concert to offer support to the Robin Hood Foundation, which is a New York City organization known for fighting poverty.
