Jack White has been named the official ambassador for Record Store Day 2013, which will take place on April 20th at independent record shops across the world. To announce the news, White took a camera crew on a field trip to United Record Pressing in Nashville, where he offered up a few fun facts about how seven-inch and 12-inch records are made, along with a handful of conspiracy theories strategically drowned out by noise from machinery in the pressing plant, which handles vinyl for White's Nashville-based Third Man Records. It's not exactly clear what pressing vinyl has to do with "the Masons and the NBA draft being aligned with each other," or his theory that you shouldn't donate blood on a Tuesday "because that's when they change the needles out," but he seems pretty confident about both.
