Sia Calls Christina Aguilera The “Mad Scientist”

Sia Furler chatted online with fans at Gigwise.com last week, where she talked about writing with Christina Aguilera on her ‘Back To Basics’ follow-up. “Xtina and I completed 4 songs together with my mate and co-writer Sam Dixon,” Furler said. “We will be credited as co-writers, and I guess I did some vocal production and Sam did the other production. I call her the Mad Scientist because she is the most technically brilliant singer I’ve ever met. She scrambled my mind.”
