Bill,
good luck to him and his band. What they are trying to accomplish isn't easy and life lessons can be hard and come from unexpected directions.
My son is involved with a few major artist, one pop another rap. Even at their level its 16 hour days 30 days on 2 days off, and both artist are the top of their music genre. My daughter is taking a break from the entertainment law firm is was interning at. Their client's include include metalica and the kid who invented guitar hero.She had heard stories about how difficult it can be. Both kids say that the one common factor is that the artist is driven to excel in their field and never quits no matter what anyone says.
Good luck,
and its OK to be a proud father,
good on ya,
Jeff
