Grimes: She's so unusual -- but in a good way. Grimes seems to borrow equally from medieval music and synth-pop, striking a synergistic sound that spurred Tastemaker Magazine to describe the vocalist as an "alien love-child of Aphex Twin and ABBA." I'll go with that -- even if I'm not exactly sure what it means. It seems like most critics are at a loss for exactly how best to describe this artist's dreamy electronica. Scribes aren't, however, lacking for accolades to toss at the artist's third release, "Visions," which many have rated among the best albums of the year. My favorite Grimes tracks include "Genesis" and "Vanessa."
