About the Song
There are songs that define a band—and then there are songs that help define an era. “25 or 6 to 4” by Chicago is both. Released in 1970 on their second album, Chicago II, this track marked a turning point not only for the group but for rock music itself. It’s bold, brassy, and unapologetically complex—a thrilling fusion of rock, jazz, and orchestral pop that manages to be both accessible and adventurous. In an age of three-minute radio singles and clear-cut categories, this song burst through the boundaries and declared that music could be smart and electrifying.
The title—“25 or 6 to 4”—may puzzle the casual listener, but its meaning is surprisingly down to earth: it refers to the time of day (either 25 or 26 minutes before 4 a.m.) as songwriter Robert Lamm sat awake in the middle of the night, trying to finish a song. That blend of everyday detail and abstract phrasing adds a layer of intrigue, but the real magic lies in the sound: a relentless, bluesy guitar riff played by Terry Kath (whose influence still resonates in rock guitar circles), combined with the explosive power of Chicago’s signature brass section. Trumpet, trombone, and saxophone don’t merely decorate the arrangement—they drive it.
Vocally, the performance is raw and urgent. The lyrics reflect the hazy focus of an insomniac artist chasing inspiration, yet there’s a universal moodiness to it all—confusion, restlessness, the tug of something just out of reach. That emotional edge, paired with the band’s unmatched musicianship, makes “25 or 6 to 4” feel both personal and monumental.
Over five decades later, the song remains a cornerstone of Chicago’s live performances and a touchstone of classic rock radio. It’s one of those rare tracks that’s beloved by musicians and casual listeners alike, admired as much for its technical brilliance as for its sheer sonic power.
To listen to “25 or 6 to 4” is to hear a band at the peak of its creative daring—taking risks, breaking molds, and laying down a sound that still stirs the soul. It’s not just a song—it’s a statement. And one that continues to echo with every blast of brass and every note of that unforgettable riff.
