This is one rock beef that’s somewhat of a mystery to almost everyone involved. From 1987 to 1994, Jay Farrar and Jeff Tweedy were songwriters together in the alt-country band Uncle Tupelo. They were poised for mainstream success when suddenly Farrar quit the band in which he served as lead singer. Tweedy and the other members of the band were mystified and Farrar was tight-lipped. In 1995, he told No Depression magazine, “It just seemed like it reached a point where Jeff and I really weren’t compatible.”
