Lady Gaga goes jazz: Listen to live version of "Lush Life" from Tony Bennett duet album

This fall, Lady Gaga and Tony Bennett join forces for a jazz duet record called Cheek To Cheek. The album doesn't have a set release date yet, but it's rumored to consist of covers and a couple of original tunes. 

Recently, the pair previewed tracks from the record at the legendary Montreal Jazz Festival. A few live recordings are floating around on YouTube, including this video of "Lush Life," a Nat King Cole tune. Gaga takes the reigns on this one and the results are stunning. You've never heard her sing like this.
