Donnie Dacus clearly felt his moment had arrived after moving from largely uncredited work with Stephen Stills to the spotlight as Chicago’s new guitarist.

“The Road Goes On” works like a crescendo, providing the exclamation mark that Toto’s ‘Tambu’ was always building toward.

“Take a Chance” makes a strong case for Donnie Dacus as the right guitarist for Chicago at the time.

At first, Toto’s ‘Tambu’ didn’t grab me — with a couple of exceptions. “The Other End of Time” was one of them.

Chicago’s “This Time” is a statement of hope for the future, a hope that was sadly snuffed out on Jan. 23, 1978.

The evolution of Chicago’s “Mississippi Delta City Blues” helps us chart the more personal evolution of Terry Kath as a songwriter, arranger and musician.

While Robert Lamm’s voice has held up over the years, he’s rarely, if ever, returned to the creative vocal delivery he used on this Chicago song.

Before Tom Kelly and Bill Steinberg found songwriting success with Heart, REO Speedwagon, Madonna and others, they put out an album as I-Ten.

Toto’s “Only You” is powered by a heart-wrenching vocal by Steve Lukather. He doesn’t merely sing the lyrics; he emotes them.

I know “If You Leave Me Now” was Chicago’s first No. 1 hit, but maybe they should strike it from the setlist permanently.
