Jeff Mangum stands amid the shadows in the realm of indie rock despite, or perhaps because of, writing what some consider to be one of the greatest — if not the greatest —records of the 1990s and beyond. Neutral Milk Hotel released the surreal yet personal In the Aeroplane Over the Sea in 1998, and disbanded shortly thereafter. Mangum, the band’s fountainhead, turned to reclusion. There were rumors of a nervous breakdown. He refused interviews. The press bandied about comparisons to J.D. Salinger, apt except that after a while, Mangum started making very sporadic appearances. A surge of shows featuring Jeff alone on stage with his guitar and his otherworldly voice have flowed through the last few years, with each new tour carrying more rumors of an end to Jeff’s live excursions. Will this year be Mangum’s last? Maybe, maybe not. I bet even Jeff himself can’t answer that question. Mangum hits Orlando this Saturday with Brooklyn’s Tall Firs, and tickets to the show are already sold out. Find a friend who has a spare.
