I’m a fan of Death metal and Black metal. Also Sludge and Hardcore. So, don’t know should I recommend something... But considering we are on audiophile forum, if you want to try something good on vinyl, and something that will not cause blood from your ears, try Gojira, Deftones, Marilyn Manson, their’s vinyl presses sound amasing. I also admire Metallica’s DMMs 45rpm presses, early presses by Pantera and Slayer.
Many times mentioned here Iron Maiden, my favorite album is Piece of Mind, also sounds great on vinyl by the way. If you don’t want to listen to the whole album, try Flight of Icarus song. Another great heavy metal is Metal Church. And my top heavy metal album is Rainbow Rising.
If I had to choose one song, let it be This Love by Pantera.
