I just saw this article:
Esperanza Spalding, a jazz bassist and singer/songwriter, announced at the end of July that in September she will write and record an album in 77 hours, all streamed on Facebook.
Interesting timing, no? Neil surely began official preparations for Out of Silence many months before this August. I wonder if Esperanza (massively talented btw) caught wind of this somehow? She doesn't mention Neil in the interview but you have to wonder. Her project is ambitious but smaller in scale (she's not using 35 musicians for her album, that I know of) so I'd assume her project was conceived and finalized after Neil's.
