Just from looking at the guys in Capital Cities, the L.A.-based synth pop band that played a sold out show last night at House of Blues Cambridge Room, it wouldn’t be hard to detect that the front men used to be jingle writers. With their shiny black silk jackets, singers Ryan Merchant and Sebu Simonian looked like a couple of nerds who stumbled into a band. And that’s not far from the truth as their self-titled and self-released 2011 EP turned them into an Internet sensation of sorts. While the live show was ultimately nothing more than a rather primitive synth-dance party, we can’t complain too much if the guys know how to have a good time and throw a good bash.
