Although the 17-year-old singer-songwriter is from Seattle, he's been living in L.A. working on his new album and acting career. Naturally, he fell in love with his new surroundings and wanted to write a song that brings summer to wherever the listener is.
"Filming the 'Summertime' video was a really cool experience," he tells JSYK. "I got to hang out with all of my closest Cali friends the whole day at Venice beach, walk the boardwalk, eat pizza, skim board, play beach soccer, and have a big beach party."
The video also features School Gyrls star and group member Mandy Rain, who Mathias met through the Nickelodeon project. "Mandy and I have been very close friends ever since we met on set of my first TV movie, School Gyrls, and I always look for opportunities to work with my good friends. When we were writing the treatment I made sure to make Mandy a part of it."
