With a new posthumous Johnny Cash album titled ‘Out Among The Stars’ due on Monday, Cash’s son John Carter Cash has revealed that there is still enough unreleased material from the legend to fill a further ‘four or five’ albums.

Talking to The Guardian, Cash shed some light on this as yet unheard horde of tracks, and said there were definitely plans afoot for more releases. But, wishing to side-step accusations of opportunism or cashing in (ahem) on his father’s legacy, he also admitted “some of it may never see the light of day”.
