“I wanted to let you know about a new artist from New Jersey called Lana del Rey,” it says here. “Born in the rural town of Lake Placid, New York, Lana then relocated to a series of places – Alabama, New Jersey and New York city, but now spends most of her time in London. She’s set to play her first ever UK show at The Great Escape this week at Gold Dust Club”.
