Deluxe Edition features a bonus disc of unreleased demos

Alanis Morissette was just a few months shy of her 20th birthday when she started recording the seminal 'Jagged Little Pill.'

This year, the legendary album has reached that same landmark. To celebrate the double-decade milestone, the multiple Grammy-winning singer-songwriter has remastered 'Jagged Little Pill,' which is released in several repackaged editions of her debut. It's an album that's sold more than 33 million copies around the world and ranks as one of the best-selling albums of all time. In Australia, the album sold in excess of one million albums, spent 10 weeks at #1 and was the highest selling album in 1996.

"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," says Morissette. "Thankfully, these songs have stood the test of time for me, and in their timelessness, I am thrilled to honour and reflect on them as well as the last twenty years of my life and career."

In addition to selecting music for the set, Morissette dug into her personal collection to include never-before-seen photos and other ephemera from the time. She also contributes a new essay reflecting back on this time in her life along with stories behind the 10 demos she recorded between 1994-98, all of which are making their official debut here on disc 2.

The track "The Bottom Line" is possibly the most historically significant — it's the first song Morissette and album producer Glen Ballard wrote together within an hour of their very first meeting in 1994. Other early tracks from those sessions include "Superstar Wonderful Weirdos" and "Closer Than You Might Believe." Also featured are several tracks Morissette wrote while touring the world and ascending into a global phenomenon following the album's release including King Of Intimidation and Death Of Cinderella.

Ballard also oversaw mixing and mastering for this collector's edition. "Twenty years has not diminished the energy and excitement we captured on these recordings from 1994," says Ballard. "It's been a joy to sit with these tracks after two decades and to find them in such good shape. The power of digital recording gives us this time machine and, although we are twenty years older, this music still sounds fresh!"
