Bill Frisell’s love of American country music is well documented and has informed even his most straight-ahead jazz albums. On Nashville, he goes whole hog: accompanied by bluegrass luminaries like Ron Block (banjo), Jerry Douglas (slide guitar) and Adam Steffey (mandolin), he creates a program of mostly original country tunes with a jazz undertow. The three covers are songs by Neil Young, Hazel Dickens, and Skeeter Davis — beautifully sung by Robin Holcomb. This is a warm and loving tribute to music that has deeply shaped Frisell’s development as an artist.
