Chicago VI is the fifth studio album (sixth overall) by American rock band Chicago and was released on June 25, 1973. It was the band's second in a string of five consecutive albums to make it to No. 1 in the US, was certified gold less than a month after its release, and has been certified two-times platinum since. It is the first album to feature percussionist Laudir de Oliveira, who would become a full-fledged member of the band for Chicago VIII. VI is the first studio album (the other being 1975's compilation Chicago IX) to feature the original band members on the cover before the death of leader and co-founder Terry Kath. Background After having recorded all of Chicago's first five albums in New York City (except for parts of the second album recorded at CBS in Los Angeles), producer James William Guercio had his own Caribou Studios built in Nederland, Colorado during 1972. It was finished in time for the band to record their sixth album the following February, and would remain their recording base for the next four years. Robert Lamm authored half of the album's tracks, including his response to some of Chicago's negative reviewers in "Critics' Choice". James Pankow wrote the album's two hits, "Just You 'n' Me", which peaked at No. 4 on the Billboard Hot 100 chart, and "Feelin' Stronger Every Day", which peaked at No. 10. The latter was co-composed with Peter Cetera, who also wrote "In Terms of Two", and sang lead vocal on all three songs. Released in June 1973, Chicago VI was another commercial success, spending five non-consecutive weeks at No. 1 on the Billboard 200 chart in the US, and was certified gold by the Recording Industry Association of America (RIAA) less than a month after its release. It was certified two-times platinum in 1986, the first year the RIAA awarded platinum certification to albums released before 1976. The album did not chart in the UK, although the band's first three studio albums had charted in the top ten there. The album was mixed and released in both stereo and quadraphonic. The original US CD release (Columbia CK #32400) was mastered for CD by Joe Gastwirt. Chicago VI was remastered and reissued by Rhino Records in 2002, with two bonus tracks: a Terry Kath demo called "Beyond All Our Sorrows", and a recording of Al Green's "Tired of
