The year 1976 was a turning point in the career of Chicago. The group was riding high after releasing Chicago IX in 1975, which was a “greatest hits” album that spanned their first seven records (save for Chicago III, which didn’t have any big Top Ten hits on it, and the live album Chicago IV”. The hits album reached number one on the Billboard 200 and stayed on the chart for 72 weeks. However, the follow-up LP, Chicago X, would be the high-water mark as far as commerciality would go–at least, for a little while–and would see the gradual start of dissension in the ranks. The dissension notably came from the control that producer James William Guercio had on the band, who was shaping and determining the band’s fate as it became more and more popular, which some band members were starting to grow uncomfortable with. While Guercio wouldn’t be dismissed until after Chicago XI (1977), the strain was starting to show on Chicago X. “It started happening with the tenth record”, notes Walter Parazaider, the band’s saxophonist. “He didn’t want us to learn any of the production techniques. He’d go to sleep at nine o’clock, and we’d start producing the records ourselves. Or trying to.”
Some of the resentment would be thanks to the inclusion of one slow song on the album, “If You Leave Me Now”, which was such a huge hit that it more or less defined the sound of the band among radio listeners and programmers, despite the fact that earlier albums had their share of ballads. It was Chicago’s first number one single and helped Chicago X sell more than a million copies in three months. The song was so pervasive on radio upon its release that, reportedly, those tuning in in New York could hear the song playing on four different stations, each with varying formats, simultaneously. Long-time guitarist Terry Kath and keyboardist Robert Lamm were not pleased. It has been said that Kath might have quit the band over the new direction the band would pursue in the wake of “If You Leave Me Now”, had he not accidentally and fatally shot himself in the head in January 1978 in what was a drunken handgun handling mishap.
