Chicago VII is the sixth studio album (seventh overall) by American rock band Chicago and was released in 1974. It is notable for being their first double album of new material since 1971's Chicago III and remains their final studio release in that format. It features session percussionist Laudir de Oliveira, who would become a full-fledged band member for the release of Chicago VIII the following year. Background While touring in support of Chicago VI in 1973, the band began getting restless and started integrating some lengthy jazz instrumentals into their sets. While audiences' reactions varied, Chicago greatly enjoyed the experience, decided (after years of talking about it) to record a pure jazz-influenced set of tracks, and headed straight to producer James William Guercio's Caribou Ranch studios to cut their ambitious new album. Vocals aren't present on the release until track 6, twenty-five minutes and twenty-eight seconds into the album. While the sessions began well, there was soon dissension within the group about the jazz project, with, reportedly, Peter Cetera and Guercio both wary of the commercial risk of such an undertaking. While the band reasoned that some of the jazzy material was too good to throw away, the others finally relented and accepted including the more pop and rock-oriented songs that the band had composed in the meantime. Almost by accident, Chicago had another double album on their hands. Of the more conventional material, Chicago once again turned in a varied set of songs, with Terry Kath's "Byblos", named after a club that Chicago had played in Osaka, Japan, ranking among his best efforts. Robert Lamm, who was recording a solo album entitled Skinny Boy at the time, turned in several new songs, even donating his solo album's title track, featuring The Pointer Sisters on backing vocals. James Pankow came through with another success, "(I've Been) Searchin' So Long" (#9), and trumpeter Lee Loughnane succeeded on his first try at songwriting with the hit "Call on Me" (#6). Peter Cetera made the biggest strides on Chicago VII, composing "Happy Man" and "Wishing You Were Here" (#11), a lush ballad (signs of the future, taking the band even farther from their original style and sound) that features three of The Beach Boys on backing vocals and which became a big hit in late 1974. "Happy Man" was subsequently covered by Tony Orlando and Dawn on their album To Be With
