The Rollright Stones in Oxfordshire is the only major stone circle not supported by English Heritage or the National Trust, I believe. Last January, significant vandalism was done and the private individuals who manage the site cannot afford the repair cost.
A small group of individuals got together to launch a music project to raise funds for this. CDs are now available and the first of a series of gigs will happen on the 16th September. Most of the content is trad to avoid copyright issues.
For more details on any of the above, see rollright project
The participants in the project have covered the costs of recording and duplication, so apart from postage, 100% of the proceeds will go to the Rollrights Trust.
Please have a look and support the project if you feel able to. Even if you don't like the music, the discs make great coasters (but then you would need to buy a set of six...).
