Funny, fans of Blind Guardian and Helloween are exactly the people I would recommend Defender to. The album is written and played by von Segebaden of Dawn, and was released on Necropolis, which might give a hint that it's not your average Euro power metal.

AoP is far more black metal inclined than les discrets. Granted i like them too.
Yes.
Is this good?? Should I listen to it?
Epitomy of punk/hardcore.
Yes and yes.
You, my dear friend, have great taste. Those two albums are among the best Sweden has to offer in terms of PM.
