HeadCount and D’Angelico Guitars are teaming up to auction off an exclusive guitar signed by Bob Weir and John Perry Barlow. The guitar will be auctioned off on Wednesday, December 14 at “The Songs of Barlow Benefit” at the Brooklyn Bowl.

The show, which is designed to raise money for the John Perry Barlow Wellness Trust to aid the longtime Grateful Dead lyricist in his current medical battle, will find the likes of Jackie Greene, Eric Krasno, Ross James, Grahame Lesh, Rob Barraco, Amy Helm and others playing the songs of Barlow like “Cassidy,” “Estimated Prophet,” “Throwing Stones” and many others.

Proceeds from the show, as well as the webcast, will go to the JPBWT. More information on the Trust can be found here.
