After releasing its eighth consecutive gold album in just six years, Chicago embarked upon a massive stadium tour in 1975 that s considered to be one of its finest. The shows found the group at the pinnacle of its prowess, combining the jaw-dropping musicality and contagious onstage energy that made Chicago one of the most successful acts in American pop history. This two-disc set contains two hours of previously unreleased performances recorded June 24-26 at the Capital Centre in Largo, Maryland. The collection is presented in a hardbound slipcase accompanied by a foldout poster that features rare photos from the tour.
