Yeah, that's cool, but if you want the raunch, if you want the raw, if you want the updated white man's version of blues that Chicago has gifted us, as a city and as a band , it's gotta be , but oooh ahh, they ain't talkin' 'bout Chi town. How about a little bit of encouragement from Steve Winwood and friends......
Otherwise, there are way too many blues artists that need mentioning that will blow away the band Chicago (as good as they were) into the lake, sideways and upside down.
