An Italian heavy metal singer has been charged by police with attempted murder after she stabbed her guitarist during a rehearsal. Cristina Balzano, 19, the singer with Italian band Soul Cry, is said to have stabbed her 16-year-old guitarist after he made a mistake while playing a guitar solo during a band practice, reports Yahoo Music. Balzano allegedly accused the guitarist of "sounding evil" before she stabbed him. Violence is never the answer Cristina.
