10. Grimes, 'Visions'

"Pop" is an amorphous label that has evolved far beyond its originating designation of popular. Grimes is not exactly Britney. Your mom does not know who she is (at least not yet). But like Bjork before her, there is an undeniable pop sensibility underlying Grimes' bedroom electronic experiments -- consider it the sugar that helps her more eccentric medicine go down. The left and right sides of her brain aren’t exactly warring here, as the expert fusion of her influences show a visionary young woman who, at the very least, picked the right album title. -- Joshua Ostroff
