Keller Williams’ Grateful Grass release DOS, an album to benefit the charitable non-profit organization started by the Grateful Dead, Rex Foundation. The album is available for digital download via nugs.net. 100% of the proceeds will go to benefit the Rex Foundation.

The material for the album was pulled from the live recording of “Nightfall of Diamonds” which was a benefit for the Rex Foundation at The Fillmore in December of 2013. Joining Williams was Michael Kang, Jeff Austin and Keith Moseley performing bluegrass versions of Grateful Dead material.

That night, the band dug into ten tracks including “Jack Straw,” “High Time,” “Samson and Delilah,” “Althea” and more. Additional performances include “Sugaree,” “Tennessee Jed,” “Shakedown Street,” among others.
