Chicago-At Carnegie Hall (1971)

In 1971 Chicago had already released three double albums, (his first three works), something surprising and unprecedented in the history of rock music, but for that year they went even further, challenging their fans with a quadruple live album.
Recorded at different concerts at Carnegie Hall in New York during the month of April 1971, and at the insistence of producer James W. Guercio who differed from the opinion of the members of the band due to the quality of the sound, it was released at the end of that same year.
This overwhelming batch of live records is a perfect anthology of his first works, in addition to his singles "Make me smile", "Color my World" or the well-known "25 or 6 to 4".
This quadruple album would break all records by reaching third position on the North American charts.
However, fans began to ask themselves some questions; What kind of group was this that published 10 albums (three doubles and one quadruple) in three years? Did they make so many songs in such a short time? And if they initially took extreme care of their productions, as they now publish a live with a mediocre sound ?.
These issues and others led the band to reconsider their style and radically change from jazz rock to a much more commercial sound, with soft rock very close to AOR.
