Uncle Tupelo was an influential alt-country band that added a rougher punk element to country music. My favorite of their albums was their last one, Anodyne, from 1993 which has been re-released with additional tracks. Jay Farrar went on to form Son Volt while Jeff Tweedy founded Wilco with the remaining members of Uncle Tupelo. I have a separate post on Anodyne.
Factory Belt: The Unofficial Uncle Tupelo Archives is a fine site for more information. Another site is here.
