OK, I have just had a listen to your tracks
Are they any good?
That is definitely a big yes from me there! - I absolutely loved the tracks!
The 2 tracks I just listened to on your Facebook are quite different (eg "A Thing Called Life" being a boyband type pop song and "OMG" being a much rockier affair)
Although this shows your diversity I think it is important to establish your "persona" as an artist when trying to build a following to give your "fans" a definite and clear image
Are you an "angst ridden rocker" or a "clean cut pop star"?
If you define yourself clearly in your own mind you can start building your "persona"
You can then start looking at yourself (or your band) as a "product" and apply the normal marketing techniques
e.g. once you have a clear "product" you can look at your target market and work out how to get your music listened to by people you think will like it - who will then tell their friends etc.
e.g. a "teeny bopper" star might tour "under 18s" nights at nightclubs, whereas a heavy rock or indie band would target university/college student unions or student pubs
Many people don't like the marriage between music and marketing - but if you are looking to "make a mark" you increase your chances by being a little "marketing savvy"
I think you have made a great start!
