I use Spotify or YouTube to help find new music, if I spot a band mentioned that I haven't heard of, it's easy to listen to a few tracks on these services. For example, in the latest Nightshift, there is a big piece on Kanadia, who I'm seeing in just over a months time. In the article, it mentioned another Oxford band called Leader who I didn't know. Now after getting Spotify on the case, they have a new fan and hopefully another face in the crowd when they play. There are a lot of small bands who you can find on Spotify, it's just knowing where to look. YouTube played this to me the other day...
... Another band I'd never heard of, and now follow.
