I quite enjoy Mary Anne Hobbs' Rock show on Radio One. It helps me keep up with the latest shite the hooded kiddies are being fed (so I can go 'I've heard them, and they're shat'), and she occasionally plays something good, like an old Maiden or Metallica track, or maybe something off the Relapse Records roster (e.g. Nile, Mortician).
There used to be a pirate station with surprisingly good broadcast radius in Sheffield where I live. It used to play all sorts, Ragga, Jungle, Techno, House, and then, every so often, someone would come and do a slot of Thrash and Death Metal!!! Like Deicide on the radio at 10.30 on a Sunday morning and shit like that!!! It was a fucking cool station, it didn't give a fuck, and it's such a shame that these things have to close down.
I blame the broadcast licencing laws. Why should you have to have a licence?? If people don't like it, they don't need to listen to it, and anyone using the radio to commit an actual crime can be dealt with individually.
