I do a certain amount of work among Christian professional musicians in London, some of whom are in bands. The internet is very useful to them, because you can create a platform for your music for free without having to hire in agents and managers. As soon as your blog page comes up, your music plays automatically, and anyone from all over the world can listen and comment. Those listeners can then piggy-back on your page by saying how great they think your music is, thereby attracting others to listen to their music too. These people are then known as your ‘friends’.
