On an album that I often overlook, this update of a Duke Ellington standard is one that I never do. “Sophisticated Lady” sounded like a ’90s Chicago song.

This beautiful Cole Porter update finds Chicago’s Jason Scheff singing with so much passion that you’d think he wrote it.

Chicago reimagines a classic with a completely different tone and color, rather than merely rehashing a dime-a-dozen cover from the swing era.

Rather than try to cover “Dream a Little Dream of Me” the way others had in the past, Chicago took a classic and made it their own.

“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.

“Bigger Than Elvis” is a very nice if not overwhelming piece of work on a set of 12 tunes that proved Chicago was truly inspired once again.

“God Save the Queen” is perhaps the best track on ‘Twenty 1,’ and easily one of Chicago’s better post-Terry Kath songs.

Jason Scheff is a vocal powerhouse on Chicago’s “What Does It Take,” singing with so much emotion and emphasis.

“If It Were You” is a flawless song, yet Chicago left it as an deep cut on 1991’s ‘Twenty 1,’ releasing dull, lifeless ballads as singles instead.
