Barbara has been new to me this year.
It's glaringly obvious that this is major, important stuff. Although, for example, Brel and Ferré are great and truly significant it's always been a sticking point how hyper-ventilated they can be. Texture and text-wise Barbara is more subtle and the allusiveness offers a counterpoint to some of the other writer's directness.
The book says much more than the above though, and much more than I could say.
