This Norwegian pop provocateur delivers dance music at its fizziest and edgiest. Since releasing her first single in 1999, Annie has continued to move bodies while titillating minds, craftily shifting styles to evoke early-'80s Madonna, "Locomotion"-era Kylie Minogue or 21st-century Robyn. Whether snaking her deadpan coo through the middle of brain-battering disco beats or winding her way over fuzzy, indie pop guitar, she makes the act of mocking jealous girlfriends and the men they fight over so delightfully fun.
