Don't say I'm not good to you.
Found a book titled 'Divergent Streams' which can be found here via the publisher Leanpub which is worth checking out in its own right (where I suspect a few other titles might be of interest).
Attention-grabbing enough with it's pay-what-you-want model (recommend price of £0.00), the book is notable more for being easily available - not just free. As you know, I strive for content to promote on this blog which is open-access. It's not an easy thing to do, believe me.
I will confess to not having read it yet, but thought it would be a good call to promote it while it's still hot (can digital books still be hot?). The (varied) content is broken up well, with attention paid to various related content including live music (rare).
Written by a variety of contributors and edited by Kyle Bylin (who has his fingers in many a digital pie it seems), asks:
Are streaming music services, such as Pandora and Spotify, making a good enough effort to help artists find fans? What are the challenges faced by today's independent musician? Does the digital album have a future?
