Great sounding/recorded albums

Mark Knopfler's Tracker. Mostly traditional music, real instruments, well produced. Really shows off a system.

I'm not sure what you mean by "over produced" but if you want to show off your system Steely Dan's Aja is hard to beat. Their Two Against Nature might just beat it though. Some have referred to Steely Dan's work as "over produced" but they are  mistaking it for "perfectly produced".
I have heard that Steely Dan used a drum machine on one of their albums. It was not Aja which features Steve Gadd and the legendary Bernard Purdie. I think Jeff Porcaro played drums on Gaucho.

Not on any audiophiles radar, much less the vinyl crowd, but I just recently bought the Teskey Brother's Run Home Slow new album on vinyl. I don't know anything about vinyl and the vinyl part of my system is basic to say the least....old Sony direct drive, Grado Black, $50 phono pre....but this album sounds great. Better than some of my other tiny vinyl collection. I can't point to any specific feature of the SQ that stands out. It just sounds good. My attention drifts away from the system to the music. I have no idea how this album stacks up to other high end vinyl pressings but for $20 it is one of the better recordings I own. Smooth, warm, rich, natural.
