Why don't bands ever come to Swansea?

I almost an hour away from Swansea, nearly 2 from Cardiff, and it annoys the hell out of me that bands manage to go to almost every place in England but not in Wales!! Why don't bands come to places like Swansea - fair enough - some like Elliot Minor and Does It Offend You Yeah do - but none like Motorhead, MCR, Lostprophets, Hinder etc - WHY NOT?? There are plenty of venues around!!
