The American alternative rock band from Chicago, Illinois, formed in 1994. Wilco's lineup has changed frequently, with singer Jeff Tweedy and bassist John Stirratt remaining from the original incarnation. Wilco's music has been inspired by a wide variety of artists and styles, and has in turn influenced music by a number of modern alternative rock acts. The band continued in the alternative country of Uncle Tupelo on its debut album A.M. (1995), but has since introduced more experimental aspects to their music, including elements of alternative rock, and classic pop.
Wilco garnered media attention for its fourth album, Yankee Hotel Foxtrot (2002), and is Wilco's most successful release to date, selling over 590,000 copies. Wilco won two Grammy Awards for their fifth studio album, 2004's A Ghost Is Born, including Best Alternative Music Album. Wilco released their seventh studio album, Wilco (The Album), on June 30, 2009.
