That was my first thought. Most of her demos are drum machine loops, very few have live drum tracks.
That's why my 1st thought was she was recording a new song in the studio to possibly add to an expanded In Your Dreams package (including the documentary) or possibly a song that plays over the credits or something along those lines.
But it could be any number of things. A soundtrack song?? Stockpiling new demos for future projects etc. etc. It's all very mysterious and exciting.
