The band will release their second single 'Taking Over Me' on July 29 and recently shot the accompanying video in Los Angeles.
Asked about the song's story ahead of their set at Sunday's T4 On The Beach, drummer Adam Pitts told Digital Spy: "It's the opposite [to our last single]. It's falling in love. It's a happy song. It's upbeat."
Bassist Ryan Fletcher added: "It's a big summer anthem."
Speaking about what fans can expect from the music video, Andy Brown said: "It's basically a road trip and we meet some beautiful girls along the way."
Joel Peat joked: "We get girls in the video for this, by the way. Not just Andy! We all got a piece of the pie."
Brown continued: "We have a big party at the end and then we do a big performance scene in the desert, so it's going to be awesome."
Lawson also confirmed that work on their debut album is complete, but they plan to release a few more singles from the collection before making it available in full.
