This is very interesting (4th image). Fossora already feels more varied even with the clarinets, so I think for the next album we are in for a truly eclectic affair for the first time since Post. Exciting!
In the second pic she also says Medúlla and Fossora are sister albums in a way.
This excites me as Medúlla is such a great album. Also, I'm sure she had stated previously that Fossora was like part 3 of a trilogy so I'm not surprised she's already talking about taking things in a different direction in the future.
