ARIA-chart topping duo Luke Dubber (Dubs) and Angus Stuart (El Gusto), aka Hermitude, were in Japan when COVID became a stark reality. Just making it back to Australia before the borders closed, they quietly slipped up to Angus' home just outside of the Blue Mountain town of Blackheath as the rest of the world went into lockdown. The two holed up together with a pared-back music setup: a Moog Matriarch, one other synth, and a laptop. This setup was a stark contrast to their previous recording studio, which came equipped with a recording room, live room, drum room, all with gear set up and at least ten synths to play around with. As a result, the music on "Mirror Mountain" is about finding one's way, a creative spurt coinciding with a global lockdown, to find a new kind of homecoming. Catching Flies' Remix for Hermitude's “Promises" - a song that originally appeared on Mirror Mountain - transforms the upbeat dance track into an atmospheric groove.
