Last week we let Canadian sister act Tegan and Sara take over Spinner in anticipation of their Chris Walla-produced sixth album, 'Sainthood.' Today marks a big day for the twins as their album finally hits shelves, and what's more, the duo is in our Los Angeles studio filming a performance for the Interface.

Tegan and Sara's Spinner takeover isn't over just yet. All this week we'll be streaming their new album for free on our Full CD Listening Party, and we've got more exclusive videos on the way. In the meantime, check out the clips from last week as well as their previous Interface performance after the jump.
