Tracy Nelson and her band Mother Earth mixed R&B country folk and rock in the late 60s and 70s; a decidedly straight forward style miles removed from most of the acts of the era. This best of draws together 17 cuts from the band s Mercury and Reprise catalogs and features the seminal Down So Low (later recorded by Linda Ronstadt Etta James and Maria Muldaur). The package contains a personal appreciation from Al Kooper and extensive historical essay.
