Yes working in some good hotel or being a driver for a good company in London can earn you more than being in any band in Congo. Some of these basic jobs actually pay more than most high paying jobs in Africa. I have a friend who is Director of a department in a big INGO, the wife who works for a hotel in London as a chef earns more than him. The downside is that it is also expensive out there but these guys rent places as a group and hence share accommodation, bills and food costs. However, it eats into time they need to invest in building their music careers. Hence Caferoum really needs to quickly get back after raising some money, otherwise he will mess up his career if he gets comfortable playing once in a while in clubs and parties.
