You disagree in some cases you mean? It depends from case to case, like I said in a previous post, X-Dream is a 50/50 thing. And lets not forget about for instance Sven Vath, where the REAL BRAIN was Ralf Hildenbeutel. Sven has good ideas, that is all. Lets not get into The Orb, Dr. Alex P. has the ideas, but knows jack shit about studio and producing in a high end studio and is dependent on people to help him (Fact taken from Sound on Sound interview with him). I think without Youth, there would be no The Orb. Just a few examples, and there are many many more.
One that I really can not put my fingers on is Eat Static, but I guess we will see when the next uptempo album comes which is only done by Mr Merv himself
