Is there an official Neutral Milk Hotel / Jeff Mangum website?
Yes, neutralmilkhotel.net. However, it’s very rarely been updated since the late 90s. Jeff apparently had a hand in putting together the site’s content originally, but doesn’t seem to have had a direct hand in it since. The only major update to the official site in recent years was in September 2005 when a section was added selling original drawings by Jeff (which quickly sold out). The drawings were sold on Jeff’s behalf by a friend of his. Jeff doesn’t really pop up online publicly or have a public email address. Fake/hoax “Jeff Mangum” accounts on websites such as Facebook and Twitter are common, however.
