Bob Weir and RatDog will perform at the Brooklyn Bowl on June 4 with a variety of guest musicians at the HeadCount 10th Anniversary Benefit Concert. The event will also serve as a kickoff party for Mountain Jam, which begins the following day in Hunter Mountain, NY. HeadCount founder Marc Brownstein, Brendan Bayliss, Eric Krasno, Ryan Zoidis and Eric Bloom will all make appearances, with more special guests to be announced.

Tickets go on sale to the public beginning Tuesday April 22 at Noon via the Brooklyn Bowl website. An exclusive pre-sale for Mountain Jam ticketholders and friends of the official event hosts begins today. More information can be found here.

On the event, Weir (one of HeadCount’s founding board members) said, “It’s going to be big fun. It’s always great to collaborate with other musicians, and HeadCount’s tenth anniversary is a true reason to celebrate.”
