It's rather hard to get current information. I do list some clubs and sessions in Derbyshire at http://www.folk-network.com/, but my remit doesn't really extend beyond Matlock and Buxton. I can't help directly with Derby, and there don't seem to be any useful internet resources; Martin Nail hasn't found any, either. The Peasmouldia folk club used to have a web presence, but that has disappeared; I expect it went west when Doug Porter stopped issuing Folk On. The East Midlands Folk Pages appear to be completely empty.

Not very promising, but Derbyshire can be like that. We still remember the Secret Folk Festival they had one year in Chesterfield. Mind you, there must be somebody round here who lives in Derby... presumably...
