As for his vocal partner, Bennett said of Gaga: "She's a very good singer. She's not a flash in the pan. That's why I had to do these great standards. And it's really paying off because the album's so big. Now we're about to record an album of all Cole Porter songs. That'll be the second album."
It was big tho, its gold in the US already and in Australia (ARTPOP isnt) and its nominated for a Grammy too, which ARTPOP is not either. Plus they are going to perform in a sold out tour
