it was jb,and indeed werra's small america tour of 2011 was not easy combattant wise but i think now like i said those america guys i have calmed a lot,most of the violent videos are coming from france,uk,belgium,south africa...but at the same time i think congolese musicians were afraid to take the risk even though its seems more likely to suceed in america,its way too far from congo and like jb said would be a risk taking musicians who also have their families that far from home with a risk of something bad happening
