Over the years, Big Star’s 1978 album Third has been re-released, re-sequenced, and reissued as Sister Lovers. Now, all of the album’s recordings—demos, mixes, and alternate versions of songs—have been collected in one place for the first time in a package called Complete Third. It’s out October 14 on Omnivore Recordings. The collection will be released digitally and as a three CD box set with a vinyl release expected at a later date. Complete Third is 69 tracks long and 29 of them are previously unreleased session recordings, demos, and mixes. Find the cover art, the full tracklisting, and a demo of “Like St. Joan (Kanga Roo)” below (via Brooklyn Vegan). Earlier this year, members of Wilco, R.E.M., Yo La Tengo and more performed the album in Los Angeles.
