Canadian indie-pop duo Tegan and Sara are gearing up for the 10th anniversary reissue of their fourth album, 2004’s ‘So Jealous.’ The special edition, ‘So Jealous X,’ will feature a bonus disc of remixes, covers and previously unreleased tracks, including ‘When I Get Up,’ which the twosome unveiled today (Nov. 24) via TIME. Take a listen below.

The demo never left the cutting room floor, but the sisters performed it live for some years surrounding the 'So Jealous' release. It will appear alongside the original album in its entirety, plus other rare tracks. The deluxe edition will also come with a book of never-before-seen photos.

‘So Jealous X’ comes a year after Tegan and Sara’s critically successful ‘Heartthrob.’ Grab it when it arrives on Dec. 23.
