As you may or may not know, I am an indie musician just like you. Like you, and I am making an assumption here, I've been trying everything under the freakin sun to promote my music online and off.
I bought the course in early December 2010. I watched every video, set-up and executed everything exactly as John (the course instructor) teaches, I've drilled John with a million questions (as you'll see in the comments if you sign-up) and put the stuff I learned to work. So far, I am really jacked-up about the results.
In about a months time – including two weeks of set-up (all working in my spare time) – I have added 50+ new fans to my mailing list, sold both CD's and singles as well as increased my following and chatter on sites like Facebook, Twitter and YouTube. And that is just a start. Some of the results aren't even in yet because some of the techniques take time to brew (for lack of a better word).
Anyway, if you are serious about building your fan list and increasing your sales, this is something you should take a look at. it is working for me. If you have any questions about it, slap them in the comments below and I'll answer them ASAP.
Disclaimer: For the record, not only am I a customer of the Music Marketing Manifesto, but I am also an affiliate. I figured it was working so well that it made a lot of sense to raise some money for future projects by helping out my fellow musicians like you.
