Close Harmony is a box set of The Louvin Brothers recordings.

Close Harmony contains 219 songs from the duo's years with Capitol, Decca, MGM, and Apollo, presented in chronological order along with session notes.

The recordings include such artists as Chet Atkins, Grandpa Jones, The Jordanaires, Jerry Byrd, Pete Drake, Floyd Cramer, Hank Garland and many others.

The annotations for the songs that accompanied the box set were expanded into a book titled In Close Harmony: The Story of the Louvin Brothers by Charles K.

[1] In his Allmusic review, Thom Jurek describes the release, concluding " Charlie and Ira took harmony singing to a new level and the creation of full-length albums far out of the sphere of one or two singles and filler.
