Back in 2012 we briefly reported on Stuart McClean's call for audio to be broadcast on FM frequency in the Galloway Forest Dark Skies Park. The third edition of that radio broadcast will be happening again for 24 hours on 27 September, and an open call for previously unheard works is out. Any audio sent in must be unreleased, and must not be available to listen to anywhere online, and after broadcast everything will be deleted via the Gutmann method (previous hard drives were wiped, beaten, burnt and buried).
Anyone wanting to hear the broadcast will need to be in the vicinity of The Grey Mare's Tail Bridge over Palnure (near Talnotry) on 27 September. Submissions should be no longer than 30 minutes long, emailed to Stuart McClean at frenchbloke[at]gmail[dot]com. Deadline for submissions 22 September. More details here.
