Folk singer-songwriter Seth Glier has released his newest music video, for his song "Love Is a Language," which touches on a very personal subject for Glier: his brother Jamie's autism.

"This song is really inspired by my non-verbal autistic brother, Jamie ... I've learned a lot from him, but one of the most important lessons he taught me is how to listen and recognizing a stranger's humanity despite the outside package," Glier says. "It's a raw emotion for me, one I haven't written about before, which is why I wanted the video to try and match the intensity. We tried to capture the energy that [we] put into it each night on stage.”

Also appearing in the video is Joe Nerney, a 62-year-old blind saxophone player. Glier met Nerney when he was 15 years old, and now, the two tour together. An upcoming run of dates is set to kick off on March 25 in Hadley, Mass., and stretch through mid-May; a complete list of shows can be found at SethGlier.com.

The Massachusetts native takes his brother's story to heart outside of music as well. Glier acts as an advocate for autism awareness through Musicians on Call and uses his talents as a LIVE! artist partner for ChildFund International.

"Love is a Language" comes off of Glier's upcoming album, If I Could Change One Thing, which is set for release on April 7. The album is available for pre-order from PledgeMusic.com, with a percentage of the proceeds going to ChildFund International.
