It says a lot about Gaga's character that she is giving Madeon a place on ARTPOP. I really don't imagine many other artists/labels would entrust an 18 year old with limited producing experience with such an important project.
So many fresh up and comers with this album. Madeon, ZEDD, Azealia Banks, Kendrick Lamar...
Maybe Gaga and Madeon were together because they were remixing one of their tracks for the Mugler show I'm hoping we get a preview like we did with Scheisse, remember the 'Anatomy of Change?'
