Decoding Chicago’s ’25 or 6 to 4′: A Timeless Rock Anthem

“25 or 6 to 4” stands as one of Chicago’s most enduring and recognizable tracks. Featured on their second album, Chicago (also known as Chicago II), the song showcases the band’s signature blend of rock and jazz elements. With Peter Cetera’s compelling lead vocals and Terry Kath’s distinctive wah-wah guitar solo, the track captures the innovative spirit that propelled Chicago to international acclaim. Upon its release, “25 or 6 to 4” climbed to number 4 on the US Billboard Hot 100 and secured the 7th spot on the UK Singles Chart, marking a significant milestone in the band’s early career.

25 Or 6 To 4

Song’s Title Meaning: The enigmatic title “25 or 6 to 4” refers to the time at which the song was written—25 or 26 minutes before 4 a.m. (i.e., 3:35 or 3:34 a.m.). Robert Lamm, the song’s writer, was documenting his experience of attempting to compose music in the early hours of the morning. ​

Recording Challenges: During the recording sessions in August 1969, lead vocalist Peter Cetera performed his parts while his jaw was still wired shut. This was due to injuries sustained from an attack at a baseball game earlier that year. Producer James William Guercio insisted on proceeding with the recording despite Cetera’s condition. ​

Chart Performance: “25 or 6 to 4” was Chicago’s first song to reach the top five in the US, peaking at number 4 on the Billboard Hot 100. It also achieved international success, reaching number 7 on the UK Singles Chart. ​

Bans and Controversies: In 1970, the song was banned in Singapore due to alleged drug references, a claim stemming from misconceptions about its lyrics. The ban extended to albums featuring the track and wasn’t lifted until 1993. ​

Influence on Musicians: The song’s distinctive riff has inspired many artists. Jason Newsted, former bassist of Metallica, cited “25 or 6 to 4” as the first rock or metal riff he learned to play. Similarly, guitarist Paul Gilbert mentioned that an early version of the song was among the first he taught himself on guitar.
