Lana Del Rey brought her always enthusiastic vocal stylings to Nirvana's "Heart-Shaped Box" last night in Australia. Seriously. You don't even need to take our word for it, because by some sheer coincidence, there was a person at this concert with some sort of technology device and they must have, like, held it up and tape-recorded the whole thing because here's this video. What do you think? Potential track for Del Rey's upcoming deluxe edition of Born to Die? New favorite song ever? Let us know in the comments, or we'll just have to assume it's your new favorite.
