Matt Vasquez of Delta Spirit played a stripped-down acoustic version of the band's hit song "California" inside the Airstream trailer studio of On-Airstreaming. The track comes from their 2012 self-titled album. In stark contrast to Delta Spirit's big, echoey sound, Vasquez's performance is simple and unplugged, and he beautifully portrays the powerful emotions in the song's lyrics. Check it out in the video above, and take a look at Vasquez's renditions of "Yamaha" and "Devil Knows You're Dead," which he also performed during his On-Airstreaming set.
