Grimes is a project by the multitalented Claire Boucher. The project appears to change by the hour, as shown by this Fader article. One thing that is constant, is the creepy and incredibly electro pop she makes. "Vanessa" is a blog hit with its child like melody and unique vocals. I think that "Oblivion" is actually a better song. "Oblivion" is more straight forward and propulsive. It relys less on Grimes unique vocal mannerism and more on song writing. Plus the synth line might be the best I have heard since MGMT's "Kids". Grimes just released a remix to Washed Out's "Eyes be Closed" and has new album coming out soon.
