Members of the Grateful Dead have selected 16 charities as beneficiaries of their upcoming Fare Thee Well 50th anniversary concerts. The band has released more than 300 tickets via a series of auctions on eBay Giving Works to benefit the organization. The auctions are now live.

Bidding for pairs of tickets to each show located in the general admission and reserved sections begin at the face value of the seats. A new set of tickets will be released every two days through the end of June, with all net proceeds split among the chosen charities.

“We are eager to support these charities – some of whom have been staples of our community for decades – while also giving fans another opportunity to obtain tickets,” members of the Grateful Dead said in a statement.

Beneficiaries include the band’s longtime affiliated charity The Rex Foundation as well as Unbroken Chain Foundation, Rainforest Action Network, SEVA and HeadCount. Each of the organizations will also have a presence at the shows located in Participation Row.
