Claire Boucher, better known as Grimes, has never been shy about her love of pop music. Her breakout full-length, Visions, was beaming with off-kilter, skittering production pre-dating the alt-pop she has helped make popular. With hula-hoopers and mimes on stage, Boucher delivered three new cuts: "David," "Sleepwalking" and "Go," a track she and fellow Canadian producer Blood Diamonds crafted together for Rihanna. All three suggested that the singer is ready to embrace a more mainstream sound, but "Go," like "We Can't Stop" before it, sounded exactly like what it is: A Rihanna reject. While clearly not the point, it was bizarre proof that Rih's perfectionism is often underestimated: Her attitude and seeming frivolity must make people believe that she hasn't cared to re-up on the fucks she supposedly ran out of so many years ago. Grimes provided, at best, dancehall pantomime that wasn't sharp-tongued enough for the bad gyal.
This is a good thing, though. While not right for Rihanna, it's possibly the song that could help Grimes completely crossover. It's hard to keep things that someone else turns down, but for Boucher, the confidence to release this herself might make all the difference. C.L.
