Sky is already recording and writing the new album. This is what she said to Billboard:
I think [the album] will be a little heavier. It's not going to be an electronic album completely - it's going to be a blend of everything.
Confirmed producers are, just like in her debut, Ariel Rechtshaid and Justin Raisen. She's also working with French DJ Gesaffelstein (that cover posted before belonged to him), Bobby Gillespie and Andrew Innes of Primal Scream.
In tour, she played a new song called "Guardian".SNIPPET 1SNIPPET 2
