Why it works

The i–VI–III–VII loop (Em–C–G–D) is one of the most powerful minor-key progressions in rock — it never resolves to a bright major home, so it stays urgent and unsettled.

The heavy version just plays those same four chords as power chords with distortion — same theory, more weight.

It's a superb first minor-key song: four easy chords that teach how a minor loop builds tension without ever letting go.
