"The main focus of this project is the truly stellar close harmony singing of Petra Haden, Rachel Haden, and Tanya Haden, who in the great folk and country tradition mesh their voices in a way only shared DNA can make possible. Their brother Josh Haden (who leads the group Spain) also plays on the album and wrote one song, and even more to the point, four tunes were written by Carl E. Haden, their paternal grandfather who was a successful C&W songwriter and drafted their dad, Charlie Haden, into the family band years before Charlie became one of the most respected and innovative bassists in jazz ... the Haden Triplets live up to their high standards on The Family Songbook, and one hopes the sisters' schedules will permit them to make another album sooner rather than later".
