While touring in support of
Chicago III, Chicago played
Carnegie Hall for a week in April 1971 and recorded all of their shows. A four-LP
box set for release as Chicago's fourth album (that distinction being responsible for the album's nickname of
Chicago IV) was the result.
Walter Parazaider told writer William James Ruhlmann that "The reason behind the live record for Carnegie Hall is, we were the first rock 'n' roll group to sell out a week at Carnegie Hall, and that was worth rolling up the trucks for, putting the mikes up there, and really chronicling what happened in 1971." Columbia were very skeptical on the risk the extended set posed, and with a decrease in royalties to counter that fear (a similar situation befell their 1969 debut,
Chicago Transit Authority), Chicago released
Chicago at Carnegie Hall that October to a mixed reaction. While the set sold very well, reaching No. 3 in the US (but failing to chart in the UK), the critics found the album too long—and even indulgent with its inclusions of tune-ups. The band themselves have remained divided through the years over the merits of the album.
Robert Lamm and Walter Parazaider defended the album to William James Ruhlmann, while
James Pankow and
Peter Cetera were not happy with the result.
Lee Loughnane said that although he thinks the album is good, there were many things he didn't like about it and that he didn't think the album should have been released. In recognition of setting Carnegie Hall records and the ensuing four LP live recordings, the group was awarded a
Billboard 1972 Trendsetter Award. Despite poor sound quality,
Chicago at Carnegie Hall, according to William James Ruhlmann, went on to become "perhaps" the best-selling box set by a rock act until the release of the
Live/1975-85 five-LP live box set by
Bruce Springsteen & the
E Street Band in 1986. On Monday April 5, 2021, 50 years to the day of their first Carnegie Hall show, Rhino Records announced a 50th Anniversary 16-CD box set called
Chicago Live At Carnegie Hall Complete. The collection includes all six shows in their entirety which were performed from April 5 through April 10, 1971, plus two matinee performances. The set was produced by engineer Tim Jessup along with band member Lee Loughnane, and was released on September 10, 2021. ==Artwork and packaging==
