I've been waiting for someone to post on this!
Comparing Books and Music - Books & Such Literary Management : Books & Such Literary Management
And while Rachelle has some good points of how Books and Music differ. I find it hard to ignore the similarities between Indie Authors and Indie Musicians and Indie Filmmakers, and that is reaching out, grassroots, connecting with your fans, making appearances where people can actually shake your hand and not gaze at you from afar, and building a fan base from the bottom up instead of advertising convincing you that thisperson is the next best thing.
I don't want to talk about the monetary differences. Because at the end of the day, money doesn't mean much. You can't take it with you when you die and it's not going to make you happy. Some of the best times of my life were when I was so poor I could only afford a head of iceberg lettuce and a package of ham each week for groceries. If you're writing for money, if your playing for money, your in the business for the wrong reasons. We do this because we love it. We hire editors and book cover artists to create a unique reading experience because we love writing and the process of putting a book together. (And I don't mean one ridden with errors, read the preview on amazon, you can usually tell if you're interested in the book and its quality before purchasing.)
We don't see Adam Levine slapping the Indie singer/songwriters on their ass with vicious words. He started a TV show for them. The only people I see who mimic this, are the Indie authors who made it big and haven't forgotten where they started.
