Random thought. Imagine going back in time to the sixties, and showing musicians like Jimi Hendrix and the Beatles styles of music that didn't exist then, like hip-hop, grunge (yeah, people don't like that term, but I can't think of a better one for what I want to refer to), heavy metal, and various forms of electronic music... Would it blow them away? Would some of them find some of the styles unpalatable? Would it send their music making down a different path? It'd be awesome if you could actually do it and see.
