Also remember that for a $25 donation, Kickstarter takes a 10% cut I believe, Amazon gets a cut and they ship the CD/Album/t-shirt to you as part of the price. Yes it's still a bit of a premium, for a CD but then again you can always wait to it gets released to the public.
I do however wonder about the likes of Amanda Palmer who took in 1.1 Million are kinda abusing the system for more than artist gain, that some serious money after manufacturing costs etc.
And even with all that money raised, she now isn't offering to pay local string and horn players that join her on stage. What's famously bouncing around the internet is the offer of Hugs and Beer to join her on stage.
With that said Alice Smith has a kickstarter going which I a backer of. Fantastic Neo soul singer from DC...
