“In the 1970s and ’80s, when current classics like Dolmen Music were new, they weren’t written down, at least not in a form even close to complete. Ms. Monk and her group were too busy singing them – living them, you could say – to sit and score them. It’s only in the past 15 years or so that Ms. Monk has turned some of her attention to preserving the pieces that she wants to survive her.”
