The frustrating part about Chicago’s underrated ‘Night & Day: Big Band’ is that not many people – even long-term fans – ever heard it.

Chicago’s terrific remake of the driving Duke Ellington favorite “Caravan” sounds both classic and very modern.

This doesn’t sound like the vintage version of Chicago, but it feels like they’re having fun for the first time in many years.

By the time “The Show Must Go On” finally saw official release, everything had changed – for the song, and for Chicago.

“Get On This” was ballsy, adventurous and risky — things Chicago had arguably not been in a long time. So, why’d they leave it on the cutting-room floor?

“Cry For the Lost” leaves listeners wondering why Chicago didn’t lean more heavily on Bill Champlin’s bonafide songwriting chops.

“Plaid” is one of the Top 3 Bill Champlin Chicago songs, and a perfect reflection of where the band was at the time of its recording.

“Here With Me (A Candle For the Dark)” wasn’t an every-day ballad, and for that Chicago is to be commended.

“The Pull” showed a lyrical depth that Chicago hadn’t been explored since the death of Terry Kath. Then it was shelved for 15 years.

This song comes from an album where Chicago was experimenting with different sounds and styles, and “Let’s Take a Lifetime” is no exception.
