Night & Day: Big Band is the eighteenth studio album by the American band Chicago, and twenty-second overall, released in 1995. It is a departure from Top 40 material for a more thematic project, the focus here being classic big band and swing music.
Following the release of 1991's mainstream Twenty 1, Chicago set about a dramatic return to the old days of artistic freedom without trying to have a hit single. The first result was Stone of Sisyphus, which was recorded in 1993 and 1994, then rejected by Reprise Records, and eventually released by Rhino Records in 2008. In response to this rejection, Chicago left the label and started up their own imprint, Chicago Records, to re-distribute their recently acquired Columbia Records output and, presumably, to release their future material. Despite this, their new "big band" project (in many ways, the root of Chicago's original sound) would be carried by Giant Records, a subsidiary of Warner Music, who also distributes Reprise.
Landing noted producer Bruce Fairbairn to helm the project, Chicago recorded Night & Day: Big Band from late 1994 to early 1995 and released it that May. Although Bruce Gaitsch played guitar on the sessions, the guitar slot would eventually be filled that year by Keith Howland, who remains Chicago's present guitarist. As a side note, Joe Perry of Aerosmith was brought in to add a solo to "Blues in the Night."
The album reached #90 in the US, on the Billboard 200 chart.
