In the forthcoming movie Dallas Buyers Club, Matthew McConaughey plays a Texas man who illegally smuggled AIDS medication into the U.S. from Mexico in the 1980s. And in their contribution to the movie’s soundtrack, Tegan And Sara hone in on the music of the era. “Shudder To Think,” the previously unreleased Tegan And Sara B-side that they gave to the movie, is a synthpop jam that sighs and bounces like peak-era Orchestral Manoeuvres In The Dark. Listen to it below.

The Dallas Buyers Club soundtrack is 10/29, and it also includes music from people like 30 Second To Mars (whose Jared Leto also stars), My Morning Jacket, and Cold War Kids.
