music, musicianship, money, etc.
Seriously considering buying copies of Melissa Cross' "The Zen of Screaming" 1 and 2.
Too many horror stories of vocalists growling/screaming 'wrong' and seriously injuring themselves after a few years, needing surgery, etc.
For ~$60 USD+tax/shipping/etc., I mean... it's not like I'll ever visit the US for vocal coaching in-person.
