She’s done a lot of radio concerts for the BBC so it shouldn’t come as a huge surprise that someone taped some of them.
That's it exactly, and ober a 10-year period, approximately, in various configurations where accompanying artists are concerned, the most persistent being one Martin Simpson, the one BritFolk geetarist who IMO rivals Rebourn, Martyn, McTell, Graham, and even Thompson for his picking ability
and possesses an added dimension that the other lack: Martin can
slide and he slides very well indeed. I'd say his slidin' outranks that of Drake, who was a bit of a dabbler in the craft, and Jimmy Page, who while very good, sorta stuck to the American Delta Blues style, while Simpson sorta invented a slide technique that uniquely fit traditional British Folk ballads, etc. Recall in the playing of his BritFolk "traditoinals", i.e., "White Summer" and "Black Mountain Side", Pagey did not use slide technique, @least not on the 100+ concerts I have of him playing one or both on stage. @ Pagey the slide was usually reserved for "In My Time Of Dying", a number derived directly from the Black Delta Blues experience.
