Tegan and Sara "When I Get Up"

Tegan and Sara "When I Get Up"
Sister duo Tegan and Sara are celebrating the 10th anniversary of their album So Jealous with an expanded reissue, and they've unearthed one of that collection's rarities ahead of time by sharing "When I Get Up."

This soft acoustic number clocks in at less than two minutes. It includes layered vocals and romantic declarations, while the folksy arrangement comes with a hint of atmospheric experimentation. It's definitely a little rough around the edges, but that's appropriate given that this is a from-the-vaults rarity.
