The club is the best place to hear new DnB, the record shop is the next best place to hear new DnB, and while I have a lot of respect for Friction down through the years I doubt even he would say that his radio show is anything more than a very safe and middle of the road affair with the very occasional interesting guest.
He does a great job of repping the stuff that is just a hairs breadth below the waterline of the mainstream, but realistically you are only getting a pretty narrow of what is going on in DnB.
