From BBC:

A Capuchin monk, Brother Cesare Bonizzi, is the lead singer in a heavy metal band which has just released its second album. The 62-year-old monk’s love affair with heavy metal began when he attended a Metallica concert some 15 years ago.

Brother Cesare: “I do it to convert people to life, to understand life, full-stop.”
