Uncle Tupelo were the quintessential alt-country band. The Illinois quartet took the rust-belt angst that fueled bands like the Replacements and Husker Du and infused it with the high-lonesome twang of classic country. Although the band was together for less than a decade, they left a supreme legacy, with founding members Jay Farrar and Jeff Tweedy going on to major careers of their own following the band's demise--Farrar as a solo artists and also with his band Son Volt; and Tweedy as the leader of Wilco, arguably the most important American band of the late-20th/early-21st century.
