It isn’t often that bands credit Connecticut as the launch pad for their musical success. “We had a recurring DJ night in Hartford,” says Matthew Young, singer/producer for electro-pop foursome Body Language. “We would spin house music and make our own tracks and put them in our sets. That’s how we learned. It was a blast, because basically it was the only thing to do in Hartford.” Now based in Brooklyn, Body Language’s party-rocking roots are still evident. Tracks tilt between disco beats and dreamy synth chords, transporting listeners from a hazy beach to an early-’80s dance club. “They are doing new things and trying to evolve with every song,” says manager Matt Watts of Advanced Alternative Media, who linked with the group three years ago. After 2011 EP “Social Studies,” Body Language drew new ears with debut LP “Grammar,” which came out on Lavish Habits/Om Records last September and helped the band land a synch on the new HBO show “Looking.” Body Language’s members also stay busy outside of the group. They’ve remixed tracks by Toro y Moi and Savoir Adore. Drummer Ian Chang performs with Matthew Dear, while singer Angelica Bess appears on Sepalcure’s song “Outside the Lines,” featured in the 2010 film “Black Swan.” Young and multi-instrumentalist Grant Wheeler have written and produced for Passion Pit. But Body Language is currently back together in the studio, looking to expand its horizons on a summer EP or fall LP. “With our next record we’re trying to do something that isn’t derivative of disco,” Young says. “We want something entirely new — something future-based.”
