International pop music hit an event horizon in the 21st century; no longer simply riffing on American music, emerging stars in Indonesia, Vietnam and Moldova synthesized foreign influences with their own maturing pop scenes. Listening to this set can feel like stepping into an alternate universe, where everything is familiar but slightly off in a thousand ways. Chrisye nails the weepy power ballad, Malaysia’s Kru! is an exemplary boy band, and the Ukranian Ruslana packs more bells and whistles into “Wild Dances” than Max Martin could dream of.
