Sandwiched between British Steel and Scream'n, what album wouldn't be so over-looked (other than if maybe Painkiller was released in '81; then Scream'n would have been a "disappointment").
POE is a great album in and of itself. Every song has it's own groove and the rocker's rock!
A few of my faves are:
Desert Plains
You Say Yes
Don't Go
Desert Plains
and yes...
Troubleshooter
I really like them all!!!
