Tegan and Sara at Club Nokia

Tegan and Sara’s “Heartthrob” presents a believably irregular vision of how love happens, and does it with an immediacy and a directness that feel new for these Canadian twin sisters, who have built a devoted following of indie-minded fans. In “Goodbye, Goodbye” and “Drove Me Wild,” they trade homey folk-pop guitars for sparkling new-wave synths, while “How Come You Don’t Want Me” rides an ‘80s-style drum-machine beat reminiscent of the Human League hit that almost shares its title. Club Nokia, 800 W. Olympic Blvd., L.A. 9 p.m. Fri. $39.50-$49.50. clubnokia.com.
