Happy to see A Ghost is Born getting so much love. I like them all, but starting from Sky Blue Sky, I'd go to Wilco (the latest) and then work backwards. Everything after AM takes some time, but they're all well worth it.
A Ghost is Born is at the top of my list, too. It's not actually the current lineup: no Nels Cline. I loved Jay Bennett (RIP). He was a fantastic guitar player (anyone ever hear, or better yet see, Titanic Love Affair?), and he got jobbed in I Am Trying to Break Your Heart (OK, he didn't get along with Jeff Tweedy, that's fine; but to watch the other band members pile on is pathetic). But Tweedy's guitar work on A Ghost is Born is amazing--reminds me of post-Velvets Lou Reed.
