...it was part of stuff being abandoned. And since UPS was getting rid of these and no charity wanted them, management decided to give it to the employees seeing as it was a waste to just trash them. So 5 box sets were given to 5 people, one being me.
The box set, was this:
Judas Priest: The Complete (Halford) Album Collection.
Actually had this for a good 3 weeks now and have been listenting to the whole thing from start to finish (I'm up to Angel of Retribution now).
Admittedly I was not all that much into Priest (Maiden and Scorpions were more my thing) but now I'm kicking myself for not getting into them much earlier.
