Original lead guitarist Joe Perry re-joined Aerosmith in 1985, and this album marked the beginning of their hugely succesful late-eighties comeback. It didn't get nearly as much attention as "Pump" or even "Permanent Vacation", partly because it lacks the obvious pop hit, I suppose, but it is actually a very solid hard rock record, perhaps Aerosmith's best since "Rocks".
The production is excellent, the riffs are big and dirty, the arrangements lean and mean, and "Mirrors" opens with one of Aerosmith's best songs of the 80s, the high-energy "Let The Music Do The Talking".
Other highlights include the funky, mid-tempo swagger of "Shame On You", the wonderfully titled groove of "The Reason A Dog", and the gritty, riff-driven two-guitar onslaught of "My Fist Your Face", a superb slice of melodic hard rock.
And yes, Steven Tyler's lyrics are immature and chauvenistic...although it's not nearly as bad as some of these reviewers will have you believe. But if you're going to take that kind of stuff seriously, you have no business listening to Aerosmith in the first place. Better stick with the Osmonds.
