Johnny Cash

My Mother's Hymn Book is a collection of Christian spiritual songs and hymns that Cash originally learned from his mother while growing up. The album features only Cash's voice and a single acoustic guitar. This disc was released as a stand-alone disc the following year (his 89th overall album) under the same title, and peaked at #9 on the Christian Music album chart. In the album's liner notes Cash mentions that this is his favorite album he ever made.

This was Cash's final album devoted to previously unreleased performances of faith-based music and hymns, following a long string of such releases dating back to 1959 and individual singles and album tracks even before that. Tracks 6, 9 and 10 were previously recorded for Hymns from the Heart (1962); tracks 5, 11, 14 and 15 were previously recorded for Sings Precious Memories (1975); and track 7 was recorded in concert for The Survivors Live (1982). Several other songs, such as track 13, had been performed by Cash on TV or live in concert, but formal studio recordings had not yet been issued until now.

Although the images used on the standalone CD depict Cash near the end of his life, most of the recordings on My Mother's Hymn Book actually date to Cash's early sessions for American in 1993–1994 (hence the fact they only feature Cash performing by himself).
