Guest musicians on the 2007 album include Natalie Merchant, Ryan Adams and Vic Chesnutt. Each takes the lead vocal on one of the album's songs (Adams on "200 More Miles", Merchant on "To Love Is to Bury" and Chesnutt on "Postcard Blues"), and shares vocal and musical duties on other tracks. Jeff Bird, a session musician who has appeared on virtually every Cowboy Junkies album but has never been credited as an official band member, also appears.
The album was also packaged with a performance film, Trinity Revisited, and a documentary film, Trinity Session Revisited, both by directors Pierre and François Lamoureux.
In concerts to support the album, singer Thea Gilmore substituted for Merchant in some shows.
