While this collection contains already released material, "Fish Tree Water Blues" does offers enough original work to make it unique -- especially considering that it benefits the Earthjustice Legal Defense Fund's campaign to save wild salmon, ancient forests and free-flowing waterways.
"Take Me to the River" by Bob Weir's Ratdog (with Charlie Musselwhite on harmonica) is essential listening for Dead-heads. New works from J.J. Cale, Mavis Staples and bluesman Alvin Youngblood Hart are also enjoyable. Ani DiFranco's "Fuel" is an offbeat rap with a righteous message, while Loudon Wainwright III's "Hard Day on the Planet" questions authority without a trace of malice. Tracy Nelson's "Mother Earth," with the late Mike Bloomfield on guitar, is a treat. Keb' Mo' moans and wails on "Victims of Comfort."
There are also some worthy collaborations: John Hammond supporting John Lee Hooker, and Branford Marsalis jamming with guitarist Joe Louis Walker. Earth mother Etta James is left to close with a version of the Eagles' "Take it to the Limit."
