When he hasn't been touring or protesting, Jeff Mangum has been prepping a really strong lineup for the All Tomorrow's Parties music festival. But now the event scheduled for December has been moved to March due to "unforeseen circumstances," and the bands originally handpicked by Mangum—including Superchunk, Olivia Tremor Control, and The Raincoats—might not be able to make the new dates. ATP is currently trying to keep the same group of acts in place, and will release a preliminary lineup on Nov. 10. [via Tiny Mix Tapes]
