Much like Owl City — or any number of bedroom projects started by former scene kids — Canadian electronic artist Lights clearly boasts a past that includes pop-punk and other recently popular rock styles. Her singing borrows the alternately pinched and drawn-out vowels and other stylized vocal inflections of the postpostpostpostwhatever rock circuit, and her song structures are clearly pop. Still, she's wisely managed to update them all with technological bells and whistles and a slightly more mainstream-friendly slickness, making her nearly a household name in her homeland. She's now coming to conquer the United States with a club tour, which stops at Culture Room on Sunday. Support comes from Ambassadors, a Brooklyn quartet whose members originally met as students at the artsy New School and who draw from a heavy Police influence.
