You are getting a one sided view from DI.fm, it's very centered around the continental europe based trance scene.

Try listening to some http://rinse.fm shows, particularly the Dusk and Blackdown show. Rinse is the top dog of london pirate radio.

Blackdown's blog is here: http://blackdownsoundboy.blogspot.com/

For more about the UK scene, see the writings of Simon Reynolds: http://www.thewire.co.uk/articles/2009/
