At this weekend’s Dead & Company shows at Madison Square Garden, HeadCount will once again host Participation Row featuring a half-dozen charities that will organize in a specific area.

To support the charities, D’Angelico guitars and Remo have donated custom made Dead & Company items to be signed by the band and auctioned in select cities throughout the tour.

Participation Row will live outside sections 108 to 118 at the venue. For every socially conscious action completed, the attendee’s name will be entered into a raffle to win a Dead & Company tour poster signed by the band, which features John Mayer, Bob Weir, Bill Kreutzmann, Mickey Hart, Oteil Burbridge and Jeff Chimenti.

Organizations featured include the Grateful Dead’s Rex Foundation as well as Love Hope Strength, Reverb, Mom’s Clean Air Force, Multidisciplinary Associations for Psychedelic Studies and HeadCount.
