Janet Jackson‘s Unbreakable tour started off with a bang last night in Vancouver. The legendary singer treated concertgoers to a brand new, untitled song, likely off of her upcoming album, that features Missy Elliott.

Debuting the song for the first time, Janet had the Vancouver crowd in a frenzy. Unfortunately, Missy wasn’t present to perform the song live with Janet, but a video screen was placed on stage, which projected an image of Missy performing the never-before-heard verse.

Thanks to the folks over at Stereogum, footage of last night’s song debut has surfaced. It’s tough to give the song a full analysis based on the quality (and the fact it was a live performance), but it sounds promising nonetheless.

See for yourself above and be sure to catch Janet on tour. Unbreakable album coming soon!
