Today, singer/songwriter/multi-instrumentalist Keller Williams and Grateful Dead’s Rex Foundation release DOS.  DOS is the second Keller Williams’ Grateful Grass album to benefit the charitable non-profit organization started by the Grateful Dead to give grants to a variety of worthwhile causes. DOS is available for digital purchase now at nugs.net, with 100% of the proceeds going to benefit The Rex Foundation.
 
Culled from the live recording of “Nightfall of Diamonds”- A Benefit for the Rex Foundation at The Fillmore in San Francisco on December 7, 2013, DOS features Keller Williams’ Grateful Grass with Keller (guitar), Michael Kang (violin), Jeff Austin (mandolin), and Keith Moseley (bass) performing not-so-traditional bluegrass versions of  beloved Grateful Dead songs.  Among the ten tracks – “Jack Straw,” “High Time,” “Sampson and Delilah,” and “Althea.”  View the full track list here.
 
DOS is the third album released by Keller Williams to benefit the Rex Foundation. Grateful Grass’ 2008 recording, REX (Live at the Fillmore), and Keller’s 2013 solo release, KEYS: A collection of Grateful Dead Covers on Piano, have raised tens of thousands of dollars to support the grants Rex Foundation distributes to grassroots non-profit programs. “Keller's contributions to Rex have been significant and worthwhile,” says The Grateful Dead’s Mickey Hart. “We have deep appreciation for the help he has provided in serving the community we all care about.”
 
For Keller, it’s his honor to participate in Rex Foundation projects. “They are all about music, creativity, and community,” he explains. “It makes giving to a great cause, great fun - and it’s a perfect excuse to play Grateful Dead music."
