Tegan And Sara Teleport Back To The '80s In 'Shudder To Think,' From The 'Dallas Buyers Club' Soundtrack

Listen to Tegan and Sara's "Shudder To Think" b-side.

Tegan And Sara take us back to the '80s on the ultra-synthy "Shudder To Think."

Honestly, no one does twinkling '80s pop better than twin sisters Tegan and Sara. After releasing synthy singles like "Closer," "I Was A Fool," and "Goodbye, Goodbye" from their 2012 album Heartthrob, it seems sort of fitting that our favorite ladies of the asymmetrical haircut would join the Dallas Buyers Club soundtrack with a new period-appropriate single called "Shudder To Think."

Listen to Tegan And Sara's "Shudder To Think" after the jump.

A previously unreleased T&S b-side, "Shudder To Think" has the Canadian sisters doing what they do best: singing their plaintive little hearts out next to bouncy layers of danceable synth. Trading verses about the trials involved with making a real human connection, Tegan and Sara sing, "Sometimes in this world you don't find you match/ Strangers in the street they don't meet your eye/ What will satisfy?"

Though "Shudder To Think" is a buoyant track that would be welcome on any and all '80s-themed playlists, "The Dallas Buyers Club"'s plot is a tad less cheery: Matthew McConaughey plays Ron Woodroof, an AIDS-diagnosed Texas man who manages to smuggle black market antiretroviral meds from Mexico to sell to other patients. Along the way, he teams up with a virtually unrecognizable Jared Leto, who plays a transgender woman named Rayon.

Premiering the track on Rolling Stone, Sara shared her excitement at joining the film's soundtrack. "I've been very excited about "Dallas Buyers Club" ever since hearing about the film. With the soundtrack supporting such an important cause, we're very excited to contribute a previously unreleased b-side to the campaign."

Also joining the Dallas Buyers Club soundtrack? Oh, just Thirty Seconds to Mars (!), Fitz and the Tantrums, the Airborne Toxic Event, Cold War Kids, and My Morning Jacket. #NoBigDeal #YesItIsABigDeal
