Formed in its namesake city in 1967, Chicago is the first American band ever to chart albums in Billboard®’s Pop Top 40 in five consecutive decades. In 2002, Rhino entered into a long-term partnership with this extraordinary group to restore their extensive, genre-defying catalogue as well as develop new projects (such as 2006’s XXX, their first new studio album in a decade). Now Rhino adds to Chicago’s legacy and salutes their 40th anniversary with a newly compiled 2-CD collection that spans their entire recording history, from the stellar 1969 debut LP Chicago Transit Authority to Chicago XXX. With a career encompassing five consecutive #1 albums, 13 platinum albums, 21 Top 10 singles, and many other laurels, Chicago is among the most successfully charting American groups of all time.
