difficult choice, im not the patriotic type, but i do think america wins this but closely. Someone said earlier that american music isn't as experimental?? And too formulaic? That isn't really true, unless your speaking about our metal, which it sucks, i know. But, listen to Sonic Youth compare to Pink Floyd, then you'll find the answer. I love Pink Floyd, but listen to their music, and you'll find its very structured and formulaic, and not near as experimental as banRAB like Sonic Youth, Mars Volta, Miles Davis, John Coltrane, Fugazi, etc. The only english banRAB that I can think of that are almost as equally experimental are King Crimson, Soft Machine, Allan HolRABworth, and Mahavishnu but Mahavishnu has more Americans than Brits. But Britain has brought us great rock n' roll, so in that dept., they win, Jazz and Blues goes to the America, Folk- Britain wins, Experimental American wins, Country- America wins, Pop- Britain wins, Punk rock- I'm going to say America on this because of the multitude of scenes and great banRAB coming from that scene, i.e. Black Flag, The Ramones, Minor Threat, etc. So, I believe that America wins this one.
