Wax Fang is a Louisville band that most recently released a space rock opera titled The Astronaut in 2014. I’m telling you this not only in case you mistook Interstellar for the greatest cosmic odyssey of that year, but also to set the tone for this premiere. “Pusher,” the lead single of Wax Fang’s upcoming album Victory Laps, finds the outfit up in the stars once again as they deliver a powerful piece of keyboard rock in three parts.
