You simply couldn't escape this one in 1983. It was everywhere. And I think that's one of the things that unjustly hampers it over time.
Musically, some things come across dated. But, overall, a few components throw enough weight around to ground things outside of that 80s sound. Adhering to the bones of the blues, throwing in a Little Richard style raveup, sprinkling the electronics with a little desert dust - all of these elements work to reel this record in a bit. Ultimately, it's Billy's guitar work that bridges this one from modern day musical conventions to the basic blues framework always preached by The Reverend Willie G.
For me, the biggest detriment to this record was how ZZ Top embraced MTV. They became more cartoon characters than musicians. At the same time, that schtick is probably what brought many new fans to the band and led to them discovering their back catalog.
