After three years and a false start, Grimes aka Claire Boucher has returned with the follow-up to her breakthrough, Visions , and it’s a brightly colored collection of artpop magical realism. The drumline beats and sunny guitars and melodies of “California” and the title track could almost pass for something on mainstream radio, if not for Boucher’s clarion voice cutting through. Similarly, the nimble “Flesh Without Blood” might not be the most original song Grimes has put to tape, but it’s the catchiest and is damn near irresistible. Yet in between those songs we get “Scream,” which has none of the safety of her more accessible tunes, between Taiwanese rapper Aristophanes’ twisting flow and Boucher’s curdled screech. The previously released “REALiTi” throws fans of her more straightforward electro-pop a bone, though it continues with the posi vibes and influences of K-pop and early ’90s house that flow through the rest of the album. Meanwhile, “Venus Fly,” her spacey hip hop duet with Janelle Monae, is a pure delight, coming off like a futuristic art-school spin on the Spice Girls, and “Kill vs. Maim” has the feel of the drama kids taking over a pep rally with Boucher’s yelp simultaneously spirited and demented. Boucher has no use for genre boundaries and is seemingly allergic to negativity, all of which gives Art Angels an unbeatable all-embracing energy. The biggest change from Visions is that Boucher’s personality is more front-and-center; whereas that album could be more cold and cerebral in its in-between tracks, Art Angels is entirely engaging, and even its most digitized moments are stained with blood.
