This is a difficult one. Any specific subgenre of metal you can give as a hint without spoiling it?
Even with two pictures you need a subgenre. Ok it's Metalcore and I'll edit the title so it's more specific.
Honestly, even with the two clues and the genre I had no idea this was a Lamb if God song, and I listen to them frequently.
Sometimes the hints might look obvious to the poster but not the audience due to the different perspectives they approach the hints from.
