This is a list I recommended to a friend a few years ago, so I've more or less copied and pasted it here. I've taken out one or two that aren't relevant, and there may well be one or two more I've missed. I'm not saying all these will be suitable, but these are the electronic artists I've found over a fairly long period of Last.FM and Internet radio listening to discover new artists that I've liked enough to buy to own.
