Seriously? I don’t think this challenge was made for someone like me who literally grew up listening to music mostly from the 1970s and 80s. Oh, the ancient nineteen-seventies!
If we’re going to go for the 70s, we’re going full seventies–as in 1970. Chicago is one of those bands that transcends decades by actively producing new albums with some regularity for over five decades, so it might not be fair to label them strictly “70s”. That being said, their heyday was certainly during the soulful decade of bell bottoms and braids.
Taking a bluesy 60s rock and roll pedigree and combining the big band sound of decades prior, Chicago was able to create a wholly new, experimental sound that would eventually influence big-name acts later in the decade such as Earth, Wind, and Fire and Genesis.
“25 or 6 to 4” is one of those classic tracks that really deserves an extended solo section to really let the diversity of instrumentation shine–not just lead guitar, but each horn and even the rhythm section all have distinctive parts in this piece. This was one of those songs that validated being a band nerd–even though we never did play anything half as cool in an official capacity!
