According to Living Truth Ministries, "At a concert in Los Angeles, the popular group Petra played to a packed audience. A young Bible student who attended told me that after the concert the Holy Spirit convicted him and he began to cry out and sob in repentance. 'I'll never go to another Christian rock concert—never!'" Apparently, asceticism is lighter work than it used to be.
As Hubert T. Spence notes in Confronting Contemporary Christian Music, "rock music in any form, secular or Christian, is deadly: its outer banks are found in Hell, where Satan is enthroned as god."
