Live at Jittery Joe's: Live at Jittery Joe's is an album released in 2001 by Jeff Mangum of Neutral Milk Hotel to battle the high prices of bootlegs on eBay.  Filmmaker Lance Bangs recorded it at the Athens, GA venue Jittery Joe's on March 7, 1997 during a live solo performance; this location was the original Jittery Joe's at 243 W. Washington St., not one of the current locations.  Jeff had not prepared a set list, so some of the songs were chosen by the audience.  A noisy child can be heard throughout the performance (most notably during "Oh Comely").

The Black Halo features guest appearances by Simone Simons (Epica), Shagrath (Dimmu Borgir), Jens Johansson (Stratovarius), and several others.  The album was released on vinyl in the spring of 2009, along with "Ghost Opera" (2007).

The label in the form of a 7", with "Everything Is" as the A side, and "Snow Song, Pt. 1" as the B side.  The first 50 7"s pressed also featured different artwork, with each sleeve being personally xeroxed by Mangum.  The Cher Doll edition is now out of print.
