CHVRCHES' charmingly bubbly ode to (metaphorically?) killing your shitty ex, "Gun," is now getting the remix treatment, and the L.A. musician Groundislava is setting the standard pretty high with this skittery, dance-floor-ready version. We love how he edits and layers Lauren Mayberry's vocals into parts of the beat whilst keeping her most stunning lyrical entreaties mostly intact. That isolated keyboard line at the end is particularly stunning, too. Check it out.
