Life After Death Band

i want to know about the belief of the different kind of heavy metal band??(f.e death metal,black metal & …)

are they believe in god and the life after death or not??

they believe in playing Metal, and playing it Loud. Some of them incorporate all kinds of mythological and occult references in their lyrics, but I think this is more showmanship than any deeper belief. They just freaking rock. Metal Rules!
