I agree with you. I actually love Dirty Work. I just think they could make an even more badass record if they went back to basics. And maybe it's just me, but I don't need a punk rock band to sound spectacular live. I'd rather they sing their own backup vocals on stage, and two guitars are plenty for simple pop-punk songs. But I'll be fine with whatever they do.
But that is just it...they aren't a punk rock band. They could play all their own stuff...true. But honestly, it just doesn't matter to me.
