The a ghost is born EP is available now. A quick review:

Panthers: Like a Ben's Chili Bowl milkshake, if milkshakes could be moody. Feels like an intellectual predator, all tension and cool calculation.
At Least That's What You Said (Live): The guitar solo alone makes me ashamed I missed them live. And I'm talking Catholic shame.
The Late Greats (Live): A lot better than it should be for what is basically a throwaway song. Again, the guitars alone... Nels Cline really earns his paycheck.
Handshake Drugs (Live): An amphetamine to the album version's barbituate.
Kicking Television: Shit sandwich. But one made by Tweedy.

Also, Jeff Tweedy's participating in a discussion about "file sharing, free culture, and the arts" at the New York Public Library on April 7. From the Wilco website:

Jeff Tweedy and Stanford Law School professor Lawrence Lessig will discuss their opinions regarding file sharing, free culture, and the arts. Lessig wrote the 2004 book Free Culture: How Big Media Uses Technology and the Law to Lock Down Culture and Control Creativity. Steven Johnson, author of Interface Culture: How New Technology Transforms the Way We Create and Communicate, will moderate the discussion. Tickets on sale Thursday, March 17 at 10 a.m via Smarttix.com. Additional Ticket info to follow.
