Chicago is an American rock band from Chicago, United States, originally known as "The Big Thing" and later "The Chicago Transit Authority" before shortening its name. Formed in 1967, the group became famous for blending rock with brass-driven arrangements drawing on jazz and soul.
The band’s early success was cemented with albums such as "Chicago Transit Authority" and "Chicago II" and singles including "25 or 6 to 4", "Saturday in the Park" and "Does Anybody Really Know What Time It Is?". In the mid-1970s they scored international hits with ballads like "If You Leave Me Now" and later "Hard to Say I’m Sorry" and "You’re the Inspiration".
Chicago has sold well over 100 million records worldwide and remains one of the longest-running and best-selling rock groups. A major compilation, "Chicago IX: Chicago’s Greatest Hits", became a landmark release. The band has received Grammy Awards and American Music Awards and was inducted into the Rock and Roll Hall of Fame, continuing to tour extensively into the present day.
