Grateful Grass
Keller's Grateful Grass delivers anything-but-traditional bluegrass versions of Grateful Dead favorites. The project's lineup is always rotating, and has included a Grateful Grass collaboration with The Keels, as well as a memorable evening at Denver's Fillmore Auditorium featuring Keith Moseley (The String Cheese Incident) and Jeff Austin (Yonder Mountain String Band).
In 2008 Grateful Grass recorded a live performance at The Fillmore in Denver, CO. 100% of the proceeds from REX (Live at the Fillmore) will go to benefit The Rex Foundation, the charitable non-profit started by the Grateful Dead which gives grants to worthwhile causes.
