[1] Serious Business was nominated for a Grammy Award for Best Traditional Blues Album.

[2] On AllMusic, William Ruhlmann said, "Signing to the Chicago-based independent blues label Alligator Records, [Winter] staged his own comeback with 1984's Guitar Slinger, and its follow-up, Serious Business, is in the same vein.

That vein is straight Chicago-style electric blues in the manner of Muddy Waters....

He was already developing from his old mile-a-minute playing style into more of an expressive bluesman in the late '70s.

Here, the transition is complete.... Maybe Johnny Winter isn't trying to be a superstar anymore, but his striving to be a consummate bluesman is wholly successful.
