Featuring a virtuosic lineup that counted a trombonist, trumpeter, keyboardist, guitarist, drummer, bassist, woodwind expert, and several vocalists, Chicago peruses territory on its multiplatinum 1969 effort that remains singular in execution and delivery. Here, hard-driving rock gets paired with a similarly forceful power brass section that yields energetic aural cross-sections that marry loose improvisation and focused creativity like nothing heard before.
Chicago Transit Authority has its cake and eats it, too, traversing both avant-garde approaches and pop techniques. Such pioneering methods earned the group three hits – "Does Anybody Really Know What Time It Is?," "I'm a Man," and "Questions 67 and 68" – all longtime standards. Breaking down borders, the unified jazz and R&B strains speak to compositional possibilities that, arguably, initiated fusion's entrance into the mainstream.
An entrenched sense of chemistry and cohesion is tethered to the landmark songwriting. Peter Cetera's high tenor voice, Terry Kath's trailblazing guitar, and the horn section's colorful accents function as a whole, not independently of one another. Indeed, it's this amalgamation of such unified playing and personality that comes across with unprecedented vibrancy.
