While we usually think of the The Voice as being a vocal competition reserved for pop singers, over the years, there has in fact been a smattering of vocalists with much heavier leanings, who more often than not dazzle the judges with their mighty chops.
For example, earlier this year, Amin Yahyazadeh, frontman of Iranian deathcore group Out of Nowhere, took home the gold on The Voice Persia's debut season, taking home $50,000 and a record deal with Platinum Records.
