The music scene here is very different to the UK scene. UK bands just don't get the same exposure here. I was at T in the Park in Scotland last summer and i didn't know of half the bands. I get friends back home asking if i know bands and i just don't have a clue.
www.3fach.ch is a Luzern based radio station that plays a mish mash of all styles kinda reminicent of John Peel.
http://www.couleur3.ch/fr/rsr.html?siteSect=100 is another station that i've been able to pick up in the past, but don't seem to get anymore.
You'll need the net to keep in touch with UK music living in CH. If you have iTunes, go to the music store section and switch it to the Swiss store to see what's popular here. It's quite different to the UK store.
I'm up for going to concerts too, although it all does seem to revolve round ZH. Last one i was at was Snow Patol in Oct. There was a big expat crowd at that.
