Before Williams hits the road this summer, he’ll release REX (Live at the Fillmore) on April 29.

The digital only release features a performance by Grateful Grass, featuring Williams, The String Cheese Incident‘s Keith Moseley and YMSB’s Jeff Austin performing not-so-traditional bluegrass arrangements of Grateful Dead favorites live in Denver.

All proceeds from sale of the project go to benefit The Rex Foundation, the charitable non-profit started by the Grateful Dead which gives grants to worthwhile causes.
