Grimes is inching closer to the mainstream pop world. Today, she posted a picture of herself on Tumblr throwing her Roc diamond to the sky. The image came with the announcement that she's signed a management deal with Roc Nation, the entertainment company owned by Jay Z. Other artists signed to management deals with the company include Haim, M.I.A., Rihanna, Matthew Dear, Shakira, Kylie Minogue, and Timbaland.

It wasn't all that long ago that Claire Boucher was releasing her experimental pop in tiny cassette runs, but the move is not entirely unexpected given Jay Z and Beyoncé's recent interest in artier and more direct sides of the music world. Grimes has spent a ton of time professing her love of Beyoncé online. Also: at the moment, Grimes, Jay Z and Beyoncé are all exploring their own definitions of veganism.

In other news, Tri Angle artist Evian Christ recently made a similar announcement—after working with Kanye on Yeezus, he's signed with his G.O.O.D. Music for a publishing deal, as Consequence of Sound reports. Christ's debut EP, Waterfall, will still be out through Tri Angle next year.
