I have a group of friends in the UK who are big techno fans and they tend to be pretty open minded, To me though isn't it all the same genre, EDM meaning electronic dance music, techno being electronic music you dance too.. seems the same to me. Haha thats gotta get the back up on the techno fans...
Techno came out a long time ago, I think the Germans pioneered it. House was from Chicago I believe and then the UK came full cricle with Rave/ Acid house. From there we get Jungle/Drum and bass/ UK Garage (2 step) / Grime which also is influenced by Hip Hop that came out of New York. Then From Jungle we get D&B which is different from the original drum and bass. We also get DUB from reggae. Basically my point is it's all derivatives. Those with close minds would do well to realise that and get some Patsy Cline on their playlist alongside Rage against the Machine then spice it up with some Harry Nilsson.
