Talking to one of The Double before a Brooklyn gig in the summer of 2014, I was told they were going to play a “dance piece.” I wasn’t sure how to take that, but it slowly began to make sense as I watched their stunning set. The music struck an odd balance between perpetual motion and perpetual stasis: the drummer, Jim White maintained a modified Bo Diddley beat, switching between the snare and the toms after long stretches on each, while the guitarist, Emmett Kelly, stuck steadfastly to an E chord. They took the underpinning of countless rock ’n’ roll songs—the rhythm section—and decisively moved it to the foreground. It soon became clear that this wasn’t going to be the average concert of discrete songs or pieces—so the question then became how long they would sustain the groove for.
