2007 box set by Emmylou Harris
Songbird: Rare Tracks & Forgotten Gems is a 2007 box set of songs personally selected by Emmylou Harris: "I've selected not greatest hits, but personal favorites: that, with a few exceptions-have never appeared on any other compilations, but were important gems in the string of pearls that each album strives to become. Also included are special collaborations, unreleased live and demo tracks, as well as contributions to tribute projects, which I may now gather into this fold.” [4]
Discs one and two serve as a retrospective of Emmylou's solo career, including at least one song from each of Emmylou's previous studio and live albums (and two cuts from her time with Gram Parsons). Discs three and four consist of collaborations with other performers, tribute album tracks, and unreleased material. Overall, 13 of the 78 tracks were previously unreleased. The DVD collects 9 videos filmed between 1975 and 2005, plus a public service announcement for Animal Rescue.
