NIGHT JOB: And then there’s “Dog Star,” performing tonight at the new Roxbury in Santa Ana. If you haven’t heard of them, they have a strong selling point: Group leader, back-up singer and bass guitarist Keanu Reeves spends his days as a heartthrob and movie star (“Bill & Ted’s Excellent Adventure,” “Bram Stoker’s Dracula”).
