This is Father Isaac Mary Relyea giving a fantastic, soul-shaking lecture on the Four Last Things (Death, Judgment, Heaven, Hell). I just finished it, and it scared the boots off of me. He's a current Catholic priest of a very, very old school. One great part is his voice: he's a rough, masculine, straight, Brooklyn/Long-Island/New Jersey accent, no effeminate or sissy tone, delivery sounds rough but is refined. And the other is the speech itself: he is absolute, dire, and strict in his warnings about being holy.
