Go to gigs. Go to festivals. Use social media (!) get to see new bands you haven't come across before. Go to smaller independent festivals. You might not find anything at V, but you might at something like Beautiful Days. Subscribe to music feeds from people you respect with interesting musical tastes. There's lots of excellent new musicians out there doing really exciting things, but you will have to seek it out. There is life in abundance beyond x-factor, but a lot of it doesn't make playlists on national radio (and I have to include 6music there, although there is some exciting music that pops up there from time to time) Internet radio stations are good, but it depends on if you want to step beyond single genres,as they can be over-specialised.
But above all go to gigs. See people play.
