Metal or Hardcore Band without vocals?

Tweet

Hi there guys, I have been listening to metal and hardcore (form of hardrock) a lot lately. But I figured I loved bands without vocals more than others. I have been googling some, but good ones are hard to find... Something in the sort of Blood - Conciencia (thus without the vocals), cause I definetly love the music, but not the one singing the vocals... You have some advices for me dear mylotters?
