Alanis Morissette’s breakthrough third LP, Jagged Little Pill, celebrated its 20th anniversary back in June, and Rhino will recognize that benchmark with a four-disc reissue that compiles unreleased demos, live recordings and acoustic takes.

Jagged Little Pill: Collector’s Edition will boast remastered audio of the album’s original 13 tracks, 10 previously unheard demos, Morisette’s 1995 concert in London (at which time she was supported by a backing band that included Foo FightersTaylor Hawkins and Jane’s Addiction’s Chris Chaney) and 2005’s Jagged Little Pill Acoustic. The reissue will also feature never-before-seen photos and an essay written by Morissette.

A two-disc deluxe edition will also be made available, featuring the remastered originals and demos. Both Jagged Little Pill reissues are due out Oct. 30; check out the complete track list at the bottom of the page.

"I'm super excited to share this music with a whole new generation of peeps, as well as people who have grown along with me over the last two decades," Morissette said in a press release. "Thankfully, these songs have stood the test of time for me, and in their timelessness, I am thrilled to honor and reflect on them as well as the last twenty years of my life and career."
