The Canadian vocalist/keyboardist Grimes—alias 23-year-old Claire Boucher—came through Seattle a couple times last year while touring as a opener for fellow synth princesses Lykke Li and Austra. This time, she’s headlining her own tour in anticipation of her first full-length album. After releasing three EPs with the Montreal indie Arbutus Records, Grimes signed a deal with 4AD, who will put out Visions on February 21. Via Twitter, Grimes rejoiced over 4AD’s Cocteau Twins connection, saying, “goth is sick,” but her gorgeously ecstatic new single “Genesis” is actually brighter and bubblier than her previous chilly, moody material; with its scintillating synth rhythms and sparkling beats, it’s positively euphoria-inducing.
