As most reviewers agree, this is a 5 star live recording. One person gave it 1 star, yet he agrees with the other reviews? I don't know how they did it, but whoever remastered this recording did an outstanding job. The sound quality is now comparible to Chicago's other masterpiece "Live in Japan" (which for whatever reason is now out of print). If you don't have this new Carnegie Hall release... get it. If you don't have "Live in Japan"... keep looking hard and get it too, if you can find it. Both of these CD's are different, but equally outstanding in there own ways. Don't expect commercial sounding pop ballads here. These CD's are the "real deal" with the sound that "put Chicago on the map". A sound that hasn't been heard before or since. Thankfully, these recordings have preserved that sound.
