I agree entirely with Markie, re: those four songs. And er, yes, the new stuff is pretty much VU meets Duran Duran. In fact, Nick Rhodes produced the whole record. If you cannot possibly enjoy the idea of handclapping, ass shaking 80s pop joining forces with 60's psych, then don't go. It's not that they'll play all that much new stuff, it's just that the crowd's more fun if everyone dances.
But, to be perfectly honest, the Clientele are an excellent band. I love the latest record, and, were it any band other than the Dandys playing tomorrow, I'd absolutely be at IOTA. So it's a pretty tough choice.
