Singer Jamie Hartford will tip his hat to his famous father with the mid-August release of Part of Your History: The Songs of John Hartford. Singing and/or playing on the 12-cut album are Emmylou Harris, Kathy Mattea, Kim Richey, Tim O'Brien, Nanci Griffith, Jonell Mosser, Pat McLaughlin, John Cowan, Sam Bush, Bela Fleck, Norman Blake, David Grisman, Vassar Clements, Mark Howard and others. All the songs -- save the title cut, which Jamie Hartford co-wrote with Lucas Reynolds -- were written by the elder Hartford. They include his one classic, "Gentle on My Mind," and such perennial favorites as "Natural to Be Gone." Hartford's musical prominence began in the 1960s as an RCA recording artist and a regular on The Glen Campbell Goodtime Hour. He was featured on the O Brother, Where Art Thou? soundtrack album and was also a central figure in the 2001 concert documentary, Down From the Mountain. Hartford died in 2001 at the age of 63. Part of Your History was produced by John Van Meter for the New Sheriff Creative Enterprises label.
