I, likewise, did not get interested in metal until my early 30's. Before then, the only metal albums I owned were by Metallica, ha ha.
I remember listening to Reign in Blood the first time, and I had a huge fucking grin on my face with all the fast tempos and wheedly-wheedly solos on that record. That was a moment that piqued my interest for louder stuff.

"I broke it, remember? I threw it against the wall and it like, shattered."
