The long-awaited Jesus & Mary Chain boxed set is finally set for release Sept. 30 via Rhino.

The four-disc "The Power of Negative Thinking: B-Sides & Rarities" is presented in chronological order and offers a host of previously unreleased tracks, including the "Psychocandy"-era "Walk and Crawl," alternate versions of "Never Understand" and "Coast to Coast," demos of "My Little Underground," "The Living End" and "Dirty Water" and the never-before-heard "Till I Found You."

The box also sports 19 of the 20 rarities previously released on the 1988 compilation "Barbed Wire Kisses," and a cassette-sourced 1983 recording of "Up Too High."

The packaging for "Negative Thinking" is a 6-by-10 gatefold shell and includes an 18-by-24 double-sided poster featuring artwork and a Jesus & Mary Chain family tree.

Meanwhile, work continues on the band's first new studio album in a decade, a release date for which has yet to be announced.
