More on Mangum, from wiki:

Jeff Mangum (born October 24, 1970[1]) is an American musician best known for being the lyricist, vocalist and guitarist of the band Neutral Milk Hotel, as well as being one of the cofounders of The Elephant 6 Recording Company. Born in Ruston, Louisiana, Mangum, along with the other founding members of the Elephant 6, attended Ruston High School in the late 1980s. The friends shared a passion for acts of the 1960s, most notably The Zombies and Donovan, as well as an affinity for later alternative rock bands such as Sonic Youth and the Minutemen.[citation needed] They reflected these influences in the tapes they recorded and shared with each other, forming the seeds of what would become the Elephant 6 Collective. He is married to Astra Taylor, [2] known for making the documentary film Žižek! about the Slovenian philosopher and psychoanalyst Slavoj Žižek.
