I'm fascinated by, and rather in awe of, those who can make words dance,  so I really enjoyed this interview.  Was pleased to see and completely agree with Grace's comments on the value of stream-of-consciousness writing. 
I'm pretty sure I remember an earlier interview in which Grace talked about her writing  process . . . it was probably posted here on TIS as well. 
This is a good read for anyone interested in a songwriter's process, will tweet it tomorrow when the stream is more active.
