I manage a metal band. There are five band members, including a new singer we found about a month ago. The guys rent their own jam space and are trying to practice five nights a week (yes some of them have no life). Problem is everyone arrives to the practice at a different time and the end result is not much gets done. I met with the band the other night and suggested a more structured approach to practising ( 3 nights a week, three hours per night, set start and finish time ). Problem is I don't think the singer is on the same page. He kind of shrugged it off. He is older than the other band members and I am not sure has the same drive. What to do..?
