To The Grave - Hear Evil, See Evil: The Epilogue Session
If you're looking for an OG Deathcore record almost untouched by modern tropes, this is the album you're looking for. The vocalist has tons of range including, some nasty highs and powerful pig squeals that are saved for the perfect moments. The little sound design elements that exist when the band stops playing help craft a haunting soundscape for the songs to live in. Instrumentally you get everything you'd expect to hear from this subgenre: blastbeats, tremolo, chugs, ride bell, panic chords, and all the things that give you the STANK Face.
