 First of all, not all rock music has guitars. Second, Kraftwerk were krautrock and said so themselves, do your homework. Third, Kraftwerk WERE NOT the first to incorporate synthesizers; rock, pop, and classical already beat them to it, nor were they the first to incorporate ""rhythmic beats"". Not all techno is danceable, so maybe you need to rethink what ""techno"" means and the nitpicking will settle."
