Judging by the artists appearing, I'd have thought anyone taking home either of these CDs and not knowing much folk music would be pretty pleased with what they'd bought - and might even explore further. I'm not sure they'd mind or even care that some of the English acts appearing were singing songs from elsewhere: and in any case, I'd have thought purity in any form was a massively overrated virtue. I suspect they'd only start worrying about it after completely immersing themselves in folk music for many years. Which this CD could be a starting point for, for someone out there...
Cheers
