I am using Pledge Music to raise the cash I need to make a vinyl LP which has been shelved for four years due to lack of funds. As it's a solo project it can be tough to pay for things and/or risk cash on releases on my own.
If you pre-order for £10 you get the LP and digital download and vinyl copy when it comes out (including postage). There are other items for sale and some free mp3s for pledgers, but buying the LP is the most straightforward option.
No money is taken from your account unless the project is successful in hitting the £1k target and the LP goes into production.
