Merritt Graves and Skylar Funk formed Trapdoor Social while they were students at California's Pomona College. They were both in an environmental program and immediately bonded over their shared passion for keeping the planet in good shape.

They also bonded over music.

In 2012, the alt-pop group released its debut EP, 'Death of a Friend,' which also featured Jason McGerry, who plays drums for Death Cab for Cutie.

They recently released a new single, 'Science of Love,' and then headed to Bedrock Studios in Los Angeles for a special live performance of the song. You can watch the exclusive premiere of it above.

'Science of Love' comes from the band's just-released EP, also titled 'Science of Love.' And keeping with their support of environmental causes, they're donating 100 percent of the proceeds from sales of the record to funding a solar rooftop to an L.A. nonprofit that aids former gang members.
